Comparing quarterbacks in the NFL is difficult. Even though every starting quarterback carries the same position label, no two play in exactly the same situation. Each QB has different responsibilities in different schemes with different teammates. Some get great pass protection and throw to great receivers, others get terrible pass protection while throwing to teammates who couldn't catch hands in a boxing ring.

To figure out who is being helped and hurt the most, you have to look at each offense with its quarterback taken out. You have to rank the supporting casts. So that's why we're going to do.

A note on these rankings: Each team was measured under four weighted categories. Offensive Line was ranked out of 30. Offensive lines are the most important part of a quarterback's supporting cast because they determine how much pressure he faces, how expansive the offense can be and they have a huge role in balancing the offense. Coaching is ranked out of 10, taking schemes and gameplans into account. Receivers is ranked out of 20 and includes wide receivers, slot receivers and tight ends. Running Backs is ranked out of 5. Teams with one well-rounded back are more likely to rank higher than teams with backs who fill specific roles. Receiving backs are valued in this context than would typically be.

32. San Francisco 49ers

Overall: 29

Offensive Line: 11/30, Coaching 7/10, Receivers: 8/20, Running Backs: 3/5.

Chip Kelly went from being under more pressure than any other coach in the league last season to someone who is an afterthought this season. The 49ers don't have close to enough talent on offense to be truly competitive, while Kelly himself needs to re-establish himself as an offensive genius after some very questionable play-calling last season. The 49ers have issues everywhere, but the biggest problem is their lack of receiving talent after Torrey Smith. Bruce Ellington and DeAndre Smelter have potential, but even they come with significant question marks. Carlos Hyde needs to stay healthy and eradicate his preference for pushing plays outside to get the most out of his physical talent.

31. Tennessee Titans

Overall: 34

Offensive Line: 12, Coaching: 5, Receivers: 13, Running Backs: 4.

Mike Mularkey is a white flag coaching hire. He has an awful track record and everything he's said this offseason suggests he doesn't understand where the league is going or the skill set of his quarterback. The Titans are going to run the ball as much as possible after investing in not one but two bell-cow running backs with limited receiving options in the offseason. DeMarco Murray should be better away from Chip Kelly's system before Derrick Henry assumes his role. Henry and Murray should get decent service from their offensive line, but Mariota won't. Pass protection was a huge problem for the Titans last year, Ben Jones and the most expensive rookie right tackle in the history of the sport won't rectify that. Delanie Walker remains a star, Kendall Wright is an above-average receiver who needs to stay healthy and Dorial Green-Beckham needs to develop his stamina and attention to detail. Rishard Matthews offers inconsistency and explosiveness as a third, fourth or fifth option.

30. Los Angeles Rams

Overall: 34

Offensive Line: 13, Coaching: 5, Receivers: 11, Running Backs: 5.

This is Todd Gurley's offense, -- Jared Goff is just a complementary piece. Grading the offensive line was difficult for a couple of reasons. First, you never know how much Rodger Saffold -- who can be a difference-maker when healthy -- is going to play. Second, the unit has three young, talented starters who have shown flashes of talent, but are still being developed. On the outside, Brian Quick was emerging as the Rams' number one receiver two years ago before a shoulder injury nearly ended his career. Quick never looked fully healthy in 2015, but he is healthy this season, that would be a massive boost for Goff. Kenny Britt and Tavon Austin can both be effective in specific ways, but Britt has proven to be very inconsistent and Austin needs the offense to be catered to his limited skill set.

29. Philadelphia Eagles

Overall: 36

Offensive Line: 14, Coaching: 7, Receivers: 11, Running Backs: 4.

Charting for the Pre-Snap Reads Quarterback Catalogue revealed that Sam Bradford lost 55 receptions for at least 598 yards and at least two touchdowns to receiver error last season. Only four quarterbacks lost more receptions, all of whom threw more passes, and only six lost more yards. Bradford lost a reception to one of his receivers every 9.7 attempts, one of only seven players with a number below 10. The major receiver issues the Eagles faced last season don't look improved this year, but there is slightly more hope for the offensive line after the addition of guard Brandon Brooks and the increased competition on the interior. Darren Sproles remains on the roster, while he, Ryan Mathews and Wendell Smallwood have been under-appreciated in the aftermath of Murray's departure.

28. Indianapolis Colts

Overall: 37

Offensive Line: 16, Coaching: 5, Receivers: 13, Running Backs: 3.

Offseason investment on the offensive line has moved the Colts up these rankings. Ryan Kelly is a pro-ready center who will be a quality starter from Day One. Joe Haeg could start at right guard while Le'Raven Clark competes for the right tackle spot. At worst, the Colts will have Jack Mewhort starting at left guard entering the season instead of moving him back there during the season like they did last year. Coaching remains the biggest issue in Indianapolis. Andrew Luck's third offensive coordinator will only make a significant impact if Chuck Pagano allows him to deviate away from his established philosophy. Betting against Frank Gore is a fool's errand regardless of his age, but the depth behind him is questionable at best. The Colts have a lot of speed at receiver, but Luck doesn't have ball-winners who can consistently win at the catch point. Dwayne Allen could be that player as a tight end but needs to prove himself in a bigger receiving role.

27. Detroit Lions

Overall: 39

Offensive Line: 13, Coaching: 9, Receivers: 12, Running Backs: 5.

Losing Calvin Johnson was huge for this offense but replacing him with Marvin Jones was a strong response. The Lions have two high-quality starting receivers in Jones and Golden Tate, but lack depth outside and a reliable tight end. That lack of depth and variety pushes running backs Ameer Abdullah and Theo Riddick into the spotlight. Abdullah has an abundance of talent even though he struggled to make an impact during his rookie season. If he struggles again, Stevan Ridley is now fully healthy and ready to take over his role. Riddick has emerged as one of the most versatile and reliable receiving backs in the NFL. The Lions coaching staff will allow Stafford to get rid of the ball quickly, taking advantage of the YAC ability his receivers possess. That will limit the impact of their porous offensive line in the pass game, though the drafting of Taylor Decker to play left tackle should significantly improve the group.

26. Baltimore Ravens

Overall: 39

Offensive Line: 18, Coaching: 7, Receivers: 10, Running Backs: 4.

Marc Trestman talked all offseason about how he was going to maintain the principles that Gary Kubiak had established in Baltimore. Predictably, he never even tried to. Trestman's presence as the OC takes away from John Harbaugh's presence as the head coach. Losing Kelechi Osemele and Eugene Monroe shouldn't hurt the Ravens that much. Their offensive line still projects to be one of the better units in the NFL next year. It's out wide where the real problems are. Mike Wallace has completely fallen off since leaving Pittsburgh -- he has major issues tracking and catching the ball. 37-year old Steve Smith is the oldest receiver in the NFL and coming off an unforgiving Achilles tendon tear. Smith and Wallace are the big names, but Kamar Aiken should be the team's best wide receiver so long as Breshad Perriman's health continues to impact his career. The Ravens have better receiving talent at tight end than receiver with Maxx Williams, Crockett Gilmore, Benjamin Watson and the hopefully-healthy Dennis Pitta.

25. New York Giants

Overall: 39

Offensive Line: 13, Coaching: 8, Receivers: 14, Running Backs: 4.

Odell Beckham, Jr. is one of, if not the best receiver in the league. That is undeniable at this point. The Giants as a whole don't have a good receiving corps, though. Charting for the Pre-Snap Reads Quarterback Catalogue revealed that Eli Manning lost 62 receptions (fourth most in the league) for at least 563 yards (eighth) and five touchdowns (ninth). In 2016, Sterling Shepard and Victor Cruz hope to elevate the quality of that unit. The biggest issue facing the Giants offense is its O-line. Weston Richburg is the best center in the league but John Jerry and Marshall Newhouse on his right side are major liabilities, while Ereck Flowers and Justin Pugh to the left aren't much better. Fortunately, the Giants coaching staff employ a quick passing game that helps to minimize the impact of that line. The one major qualm with the coaching staff last year was their reluctance to rely on Shane Vereen, a very talented receiving back who could be the quarterback's best friend if employed often enough.

24. Seattle Seahawks

Overall: 40

Offensive Line: 10, Coaching: 10, Receivers: 16, Running Backs: 4.

The Seahawks cumulative ranking is somewhat misleading because they have a very strong supporting cast surrounding the worst offensive line in the league. That line would cripple most offenses, but the Seahawks coaching staff is very smart in how they neutralize its impact. Option runs, creative play fakes and quick throws limit how much pass blocking the line has to do. The one thing the Seahawks haven't figured out is how to best use Jimmy Graham. Even if they don't get much out of the tight end coming off of injury in 2016, they still have a huge amount of versatility and depth in their receiving corps. Doug Baldwin, Jermaine Kearse and Tyler Lockett combine explosiveness with reliable hands and precision. A healthy Paul Richardson could elevate the unit even further.

23. Miami Dolphins

Overall: 40

Offensive Line: 18, Coaching: 7, Receivers: 12, Running Backs: 3.

What is up with Dolphins receivers? Ever since Ryan Tannehill has arrived in Miami, he has dealt with an abnormally high number of failed receptions. Charting for the Pre-Snap Reads Quarterback Catalogue revealed that the quarterback lost 63 receptions (second most in the league) for at least 717 yards (second most) and at least six touchdowns (third most) last season. Kenny Stills, Jarvis Landry, Jordan Cameron and Devante Parker remain from that group. Parker should play more and will hopefully improve because of it. Leonte Carroo is in position to push Stills for playing time if the former Saints receiver doesn't live up to his potential. The offensive line in Miami has also been disastrous over recent years, but the addition of Laremy Tunsil and expected health of Branden Albert could quickly turn that unit into a strength. Letting Lamar Miller leave in free agency was a big mistake; Jay Ajayi and Kenyan Drake need to prove both their quality and durability.

22. Green Bay Packers

Overall: 41

Offensive Line: 19, Coaching: 7, Receivers: 12, Running Backs: 3.

Jordy Nelson is a huge part of this ranking. Without him, the receivers grade would plummet. Randall Cobb is a solid player, but the Packers don't have a viable third option. One of Davante Adams, Jared Cook, Jared Abbredaris, Jeff Janis and Ty Montgomery have to establish themselves. Aaron Rodgers makes everyone on that offense better, but the offensive line is an excellent unit in its own right. The strength is at the guard positions where T.J. Lang and Josh Sitton create one of the better starting tandems in the league. Bryan Bulaga could have been the best player on the line and is still a good starter, but injuries have curtailed his potential. Bulaga plays across from David Backhtiari who has his limitations, but is still starting caliber. Eddie Lacy's offseason weight loss will hopefully return him to the form we haven't seen since his rookie season, because James Starks, while explosive, has a limited overall skill set. The Packers don't boast overwhelming talent and Mike McCarthy uses a very simple, rigid scheme, so the quarterback position in Green Bay is stressed more than it should be.

21. Atlanta Falcons

Overall: 41

Offensive Line: 15, Coaching: 9, Receivers: 12, Running Backs: 5.

Kyle Shanahan is still a good coach. Matt Ryan was put in positions to be effective last year and he repeatedly beat himself. Ryan needs to play better in 2016. He will be aided by the arrival of Alex Mack, who should push the offensive line toward respectability even if he is slightly overpaid at this point. The Falcons' only real issues on the offensive line are at the guard positions. Both tackles are emerging into good starters. Julio Jones remains one of the better receivers in the league. Mohamed Sanu and Justin Hardy are decent complementary pieces, but the Falcons could use a stronger second starter. The lack of proven quality at tight end is an issue. Running backs aren't huge for quarterbacks normally, but Devonta Freeman is one of the exceptions. He is an outstanding runner and receiver but also a supremely-talented pass protector.

20. Minnesota Vikings

Overall: 41

Offensive Line: 17, Coaching: 7, Receivers: 13, Running Backs: 4.

Improving the offensive line was a focus of the offseason for the Vikings. Andre Smith and Alex Boone are proven starters who will upgrade their respective positions. The return of John Sullivan at center will also have a big impact. The Vikings won't have a great line because Matt Kalil remains a turnstile at left tackle, but it could be an above-average unit. Norv Turner didnt' help his quarterback or his offensive line last year, stressing both positions too much to prioritize Adrian Peterson. Turner has shown previously that he can adjust to cater to his quarterback and he needs to do it again in 2016. Adding Laquon Treadwell to Stefon Diggs gives the Vikings a legitimate starting combination that wasn't there last year. Treadwell's presence in the starting lineup will allow Kyle Rudolph, Charles Johnson and Jarius Wright to fit into more suitable roles as complementary pieces.

19. Tampa Bay Buccaneers

Doug Martin

Overall: 41

Offensive Line: 13, Coaching: 8, Receivers: 15, Running Backs: 5.

Only the San Francisco 49ers used six-or-more offensive linemen on the field together more often than the Tampa Bay Buccaneers last year. The Bucs also ranked sixth in first-down run percentage and ran 29 percent of the time while trailing in the second half (seventh in the league). Jameis Winston's offense had to be run that way because of how limited the offensive line is. It can run block relatively well, as Doug Martin's numbers will attest to, but pass protection in space is a major concern. Those issues should carry over into 2016, but Winston can expect more help from his receivers. Vincent Jackson can still be an accuracy-erasing presence deep downfield, while Cameron Brate was very impressive last year, so it won't matter if Austin Seferian-Jenkins lives up to his potential or not. Mike Evans is the key. Evans is entering his third season and has shown signs of greatness, but struggled with drops last year. His drops aren't a major issue regardless because he does so much else to help his quarterback, but without them he will have a chance at being a top 12-15 receiver.

18. Carolina Panthers

Overall: 46

Offensive Line: 17, Coaching: 9, Receivers: 12, Running Backs: 4.

Few teams could survive with Mike Remmers and Michael Oher as their offensive tackles, but such was the quality of Cam Newton's play in 2015. Newton allowed offensive coordinator Mike Shula to run a scheme that overstressed the quarterback to cover the weaknesses that surrounded him. The interior of the offensive line is very good, especially in an offense that relies so much on running between the tackles. Kelvin Benjamin's return to the receiving corps gives that unit a boost, but tight end Greg Olsen is still the best pass catcher on the team. Benjamin had impressive total stats as a rookie but had an outrageous number of failed receptions, something his teammates also struggled with throughout the 2015 season. The Panthers' best chance of upsetting this ranking is Devin Funchess' development. Funchess had major drop issues early on during his rookie season, but showed signs of improvement as the season developed.

17. Chicago Bears

Overall: 42

Offensive Line: 17, Coaching: 7, Receivers: 15, Running Backs: 3.

Adam Gase got too much credit for Jay Cutler's performances in 2015, but that doesn't meant there aren't concerns with the inexperienced Dowell Loggains taking over his role. Gase relied heavily on screens and quick throws to limit the impact of the offensive line. Loggains shouldn't need to do that as the Bears look set to have four quality starters after the additions of Cody Whitehair and Bobby Massie. Left tackle is the only spot with real concern with Charles Leno. The real strength of this group is its receivers. Alshon Jeffery and Eddie Royal are established. Kevin White should prove to be the perfect complement after missing his rookie season through injury. White is a phenomenal talent, a ball-winning receiver with the athleticism to run a variety of routes and stretch the defense. He and Jeffery are easy receivers to throw to because they can go up and get the ball in the air against tight coverage. The Bears should incorporate more vertical elements after losing Martellus Bennett and Matt Forte in the offseason. Especially since Forte hasn't really been replaced.

16. Cleveland Browns

Overall: 43

Offensive Line: 20, Coaching: 10, Receivers: 9, Running Backs: 4.

The doom and gloom surrounding the Browns' offensive line this offseason was too much. Mitchell Schwartz and Alex Mack were good players, but the Browns still have Joe Thomas, the consensus best left tackle in the NFL, Joel Bitonio, one of the better guards in the league, John Greco, an established starter, and Cameron Erving, a second-year player who struggled playing out of position as a rookie who should improve at center. The big problem in Cleveland is the lack of receiving talent. Corey Coleman was their first-round pick this season, but is coming from a simplistic Baylor offense, so should need time to develop. After Coleman, the Browns have Marlon Moore, Taylor Gabriel, Andrew Hawkins and three rookies. Moore and Gabriel are inadequate starters, while Hawkins is a fourth or fifth-option in an ideal scenario. Hue Jackson will need to rely heavily on tight end Gary Barnidge and running back Duke Johnson unless his young receivers develop quickly. Johnson is the most fascinating piece, as he may already be the best receiving back in the league who doesn't have a ' in his name.

15. Denver Broncos

Overall: 43

Offensive Line: 14, Coaching: 9, Receivers: 15, Running Backs: 5.

Demaryius Thomas had a rough season in 2015. Presuming he returns to catching the ball consistently this year, he and Emmanuel Sanders should once again form one of the best starting receiver tandems in the NFL. The Broncos need a third receiver to emerge. Cody Latimer has a lot of talent, but hasn't realized it yet in the NFL. He, Bennie Fowler and Jordan Norwood will compete with undrafted rookies for spots on the depth chart. Second-year tight end Jeff Heuerman missed his rookie season through injury, but will compete with Virgil Green and Garrett Graham for snaps this season. At running back, C.J. Anderson is a well-rounded player with the talent to be one of the best backs in the league. Anderson will run behind a much-improved offensive line this year after the additions of Russell Okung and Donald Stephenson. Stephenson can play guard or tackle, helping the Broncos put their best five linemen on the field.

14. Buffalo Bills

Overall: 44

Offensive Line: 17, Coaching: 9, Receivers: 13, Running Backs: 5.

Sammy Watkins' health is an issue entering the season, but that should be resolved. Watkins broke out over the second half of last season as the Bills started to be more aggressive in getting him the ball. Watkins is a phenomenal, game-changing talent who should establish himself as one of the best receivers in the league this season. Charles Clay is the Bills' second best receiver, while Robert Woods remains a strong third option. The offensive line really only needs someone to step up and solidify the right tackle spot. The line is helped by offensive coordinator Greg Roman and his willingness to embrace Tyrod Taylor's athleticism. That athleticism is complemented by LeSean McCoy, who remains one of the best running backs in the league when put in space.

13. Houston Texans

Overall: 44

Offensive Line: 17, Coaching: 8, Receivers: 14, Running Backs: 5.

Joe Philbin was fired in Miami for a couple of reasons, but the biggest one was his refusal to focus his offense around Lamar Miller. Miller is a phenomenal talent both as a runner and receiver. He should be the focal point of the Texans offense, taking pressure off the quarterback by turning short throws into big gains. DeAndre Hopkins is arguably the best receiver in the NFL right now. Not only is Hopkins extremely talented, he's extremely easy to play with because of his unnatural catch radius and consistency. Hopkins makes more difficult plays in a month than most receivers make in a year. He and Miller will carry the offense like Le'Veon Bell and Antonio Brown do in Pittsburgh, while the rest of the supporting cast only needs to be average for the offense as a whole to thrive. With that said, the rookie receivers could both have a huge impact. Will Fuller will stretch the field and Braxton Miller will provide value on plays that are specifically designed to put the ball in his hands.

12. Kansas City Chiefs

Overall: 45

Offensive Line: 15, Coaching: 10, Receivers: 16, Running Backs: 4.

Coming off a second ACL tear, it's hard to have much faith in Jamaal Charles. He was the best player in this offense and the most important player, even including the quarterback, before his injury, but the second ACL tear should be tougher to return from than the first. After Charles went down, Charcandrick West and Spencer Ware proved to be reliable, productive runners. They can't replicate Charles' talent, but do offer the Chiefs quality depth. With a limited Charles, Jeremy Maclin, Travis Kelce and Albert Wilson should be featured more over the full season. The Chiefs have two stars, Maclin and Kelce, with a lot of depth in Wilson, Rod Streater, Chris Conley, De'Anthony Thomas, Tyreek Hill and Demarcus Robinson. Andy Reid's scheme relies on a lot of misdirection and play action. This eases the pressure on the offensive line. Mitch Morse, one of the best centers in the league, and newly-acquired Mitchell Schwartz, one of the best right tackles in the league, lead that unit.

11. San Diego Chargers

Overall: 45

Offensive Line: 15, Coaching: 9, Receivers: 17, Running Backs: 4.

Health has been a major issue for the Chargers over the past two seasons, specifically on the offensive line: Five players have started at center alone over the past two years. In King Dunlap, Orlando Franklin, Matt Slauson, D.J. Fluker and Joe Barksdale, San Diego has five competent starting linemen. That's rare in today's NFL. The Chargers are also very deep at receiver. Keenan Allen was enjoying a breakout season in 2015, catching at least nine passes in four of eight games, before he was injured. Antonio Gates missed the first four games of the year but continued to outperform his age. Stevie Johnson fit in perfectly, while Travis Benjamin should be an improvement over the now-retired Malcom Floyd. At running back, there isn't a good reason to be excited about Melvin Gordon, but Danny Woodhead remains one of the most valuable receiving backs in the NFL.

10. New York Jets

Overall: 45

Offensive Line: 14, Coaching: 10, Receivers: 16, Running Backs: 5.

The Jets don't need Ryan Fitzpatrick because they have a supporting cast that can elevate other quarterbacks the way it did him. Chan Gailey is one of the smartest coordinators in the NFL who uses his creativity to create simple, safe throws that lead to big plays for his quarterbacks. In Brandon Marshall and Eric Decker you have two receivers who don't require precise accuracy to make a play on the ball, while Devin Smith is a spectacular talent who was held back by Fitzpatrick's inability to throw the ball deep before he tore his ACL during his rookie season. Jace Amaro, Quincy Enunwa and Charone Peake offer as-of-yet unrealized upside, whereas Kenbrell Thompkins is the more established backup. Depth at receiver is less important in this offense because of how Gailey will scheme his backs and tight ends open, but also because of who his running backs are this year. Matt Forte is one of the best running backs in the NFL, especially as a receiver, and Bilal Powell showed off his versatility as a complement to Chris Ivory last year.

9. Jacksonville Jaguars

Jags receivers

Overall: 47

Offensive Line: 17, Coaching: 9, Receivers: 17, Running Backs: 4.

The offensive line was an issue for the Jags in 2015, but it was an issue that Blake Bortles made worse by running into sacks and missing open reads. Adding Kelvin Beachum and welcoming Brandon Linder back from injury will elevate the overall quality of the unit. Greg Olson was an instant upgrade over Jedd Fisch as the Jaguars offensive coordinator last year. He played to his quarterback and receivers' strengths more by pushing the ball downfield regularly. This allowed Allen Hurns and Allen Robinson to prosper. At this point, Hurns and Robinson are the best starting wide receiver tandem in the NFL. If Julius Thomas hadn't eaten his signing bonus last year, they'd have a legitimate threat at tight end. Instead, the Jaguars need to look towards Marqise Lee and Rashad Greene to emerge as dangerous slot receivers.

8. New Orleans Saints

Overall: 48

Offensive Line: 22, Coaching: 10, Receivers: 12, Running Backs: 4.

At this point, it looks like Andrus Peat will play guard for the Saints. Terron Armstead is one of the best left tackles in the NFL and Zach Strief is a quality starter at right tackle. Peat at guard will allow the Saints to put their best five offensive linemen on the field. With Max Unger starting at center, the Saints project to have four above-average starters on their O-line. The quality of that line and Sean Payton's brilliance in scheming receivers will allow Drew Brees to continue to thrive, even his career winds down. Michael Thomas and Coby Fleeener were the two big additions to the offense in the offseason. Thomas will fit the Marques Colston role perfectly. Fleener has major drop concerns but has the athleticism to fill the vertical tight end role that typically thrives in Payton's scheme. The real pivot player for this offense is C.J. Spiller. Spiller was one of the most explosive and dangerous receivers in the league at one point in his career. He never realized his potential in Buffalo and looks set to follow the same path in New Orleans.

7. Arizona Cardinals

Overall: 49

Offensive Line: 18, Coaching: 10, Receivers: 17, Running Backs: 4.

Playing quarterback for Bruce Arians can't be much fun. Arians asks his QB to do a lot while absorbing hits repeatedly. Despite that, Arians also gameplans very well and gives his quarterback the freedom to rely on the plays that he is comfortable with. The aggressiveness of Arians' philosophy demands receivers who can get downfield in a hurry. John Brown and J.J. Nelson are two of the fastest receivers in the league, Michael Floyd is no slouch either. Those three allow Larry Fitzgerald to fill more of a possession role, but even he can get open downfield with his route running before winning at the catch point. David Johnson is a popular pick as a breakout player in 2016. He has all the athleticism to thrive in space but needs to prove he can carry a bigger load and show off the nuances that are required to sustain success at this level.

6. New England Patriots

Overall: 52

Offensive Line: 19, Coaching: 10, Receivers: 19, Running Backs: 4.

The Patriots are the only team in the league who can run the ball 50 times one week before passing it 50 times the next without suffering for it. Bill Belichick's ability to recognize and attack an opponent's weakness puts his players in the best position to succeed. That is what allows him to get the most out of the talent available to him. This Patriots offense boasts a lot of talent. Rob Gronkowski alters gameplans with his presence alone. Martellus Bennett is the second-best tight end on his team but one of the best in the league. Those two, along with the elusive Julian Edelman and Danny Amendola (coming off a very impressive season), gives the Pats the best receiving corps in the league. Chris Hogan, Nate Washington, Aaron Dobson and Malcolm Mitchell offer impressive depth as well. Issues on the offensive line impacted the Patriots last year, but those issues were mostly about health. The return of injured players and offensive line coach Dante Scarrnechia will make that unit one of the better groups in the league.

5. Cincinnati Bengals

Overall: 54

Offensive Line: 27, Coaching: 7, Receivers: 16, Running Backs: 4.

The Bengals had the best supporting cast in the NFL last year. Losing Hue Jackson, Marvin Jones, Mohamed Sanu and Andre Smith hurts, but the offense still has an outrageous amount of talent for Andy Dalton to rely on. Only two teams in the league have better offensive lines than the Bengals, with Andrew Whitworth, Kevin Zeitler and Clint Boling leading the way. Cedric Ogbuehi or Jake Fisher will replace Smith at right tackle, though suggestions that center Russell Bodine could be replaced have been dismissed. Bodine is the one weak link on the offensive line. Losing Jones and Sanu from the receiving corps is rough, but A.J. Green and Tyler Eifert pose matchup problems in every game they play, with Brandon LaFell, Tyler Boyd and Giovani Bernard acting as competent complements. A darkhorse is tight end/fullback Ryan Hewitt, who flashed athleticism and comfort as a receiver on the few opportunities he received last year.

4. Pittsburgh Steelers

Overall: 54

Offensive Line: 24, Coaching: 10, Receivers: 15, Running Backs: 5.

Martavis Bryant's season-long suspension for violating the league's substance abuse policy leaves the team without its best deep threat. However, the Steelers are so talented that they still rank in the top five of supporting casts without Bryant and left tackle Kelvin Beachum. Beachum was replaced by Alejandro Villanueva after he was injured last year. Villanueva proved to be reliable, rounding out an offensive line that features one of the best interiors in the NFL. To replace Bryant, the Steelers will rely on Markus Wheaton and Sammie Coates more, but tight end/receiver Ladarius Green could be the primary deep threat. Green has great athleticism, length and ball skills that were never thurst into the spotlight in San Diego. Every piece on this offense is secondary to Antonio Brown and Le'Veon Bell. Brown has a rounded skill set and is as consistent as any receiver in the league. Bell is the best running back in the league and the best receiving back in the league. They'll make it especially difficult for other teams to be aggressive in terms of disguising coverages or blitzing from the second level.

3. Washington

Jordan Reed

Overall: 55

Offensive Line: 23, Coaching: 10, Receivers: 19, Running Backs: 3.

Jordan Reed was one of the biggest breakout stars of 2015. Reed finally stayed fully healthy and got the service he needed to show off his talents; his size, athleticism and ball skills proved to be uncoverable at times. In the draft, Washington added a wide receiver with the same attributes to pair with DeSean Jackson, Pierre Garcon and Jamison Crowder, who was more than just a pleasant surprise as a rookie. The Washington receiving corps is very easy to throw to because they are extremely consistent, dynamic in space and offer a wide catch radius. The offensive line offers less individual talent but as a unit played extremely well last season. Washington doesn't get a 10 for coaching just because of Jay Gruden -- the work of offensive line coach Bill Callahan was clear to anyone who followed this offense closely enough last season. All that Washington is missing is proven talent at running back.

2. Dallas Cowboys

Overall: 57

Offensive Line: 30, Coaching: 9, Receivers: 14, Running Backs: 4.

Putting Ezekiel Elliott behind an offensive line that essentially features four first-round picks is unfair. Elliott will be able to replicate and even improve on what Murray achieved two years ago behind a slightly less-talented line. With Dez Bryant as a mismatch problem outside, a healthy Tony Romo should have one of the easiest roles of any top quarterback next season. What Romo will need to do is elevate the other receivers in his offense. Jason Witten has declined dramatically over the final stage of his career, while Terrance Williams has never lived up to expectations. Cole Beasley and Brice Butler could thrive with Romo, if the quarterback is given the kind of pass protection we expect. This team is extremely talented, even if most of the defense will be suspended by the time the season starts.

1. Oakland Raiders

Overall: 58

Offensive Line: 28, Coaching: 10, Receivers: 16, Running Backs: 4.

The hiring of Jack Del Rio and subsequent hire of Bill Musgrave was a source of hilarity last offseason. Del Rio and Musgrave had both failed previously in their respective roles. Twelve months later, Del Rio has the Raiders on the rise and Musgrave's finger prints on the offense can be seen. Musgrave understands perfectly the skill set of each individual in his offense, calling plays and creating gameplans that get the most out of his available options. In 2015, the Raiders had one of the best offensive lines in the league until injuries hit over the second half of the season. They retained all the key pieces of that line but also added one of the best guards in the NFL: Kelechi Osemele. Nobody could touch Derek Carr last year, so Osemele's real value will be as an impact run blocker. The offensive line combines youth and experience, something that can also be said about the receiving options. Michael Crabtree's rebirth in Oakland earned him a contract extension last year, while Amari Cooper lived up to expectations despite his struggles with drops. Cooper creates enough yards with his feet to make up for the plays his hands leave on the field. Seth Roberts is a very talented slot receiver, while Andre Holmes and Clive Walford are tall field stretchers.
