After Week 1 wrapped, we focused on what could have been reality or myth following the sample size of a single game in 2017. It's not enough to judge how a player will do all season, and neither is two games. But at least two games is twice as many as one. I'll always take double the sample size when offered.
The NFL is indeed offering us another week of games, though two of these teams will be playing for the first time this season. Even players on the Bucs and Dolphins have something to prove in Week 2, and this is what the focus is on now. For better or for worse, after a good game or a horrible one, who will prove that their Week 1 game was or wasn't a fluke?
After Thursday's Texans-Bengals game, there are still 15 games left and 30 teams in action for Week 2. These are 30 players who have a crucial "prove-it" game ahead of them.
Eagles at Chiefs
Philadelphia: Brandon Graham, DE
Graham was a dominant defensive end last season, finishing second in the NFL with 49 QB pressures, but he remains under-discussed as a premier player because of his 31 sacks over eight seasons. That could change if he builds on Week 1. Graham had two sacks in Philly's win over Washington, and another double-digit sack performance would get everybody's attention.
Kansas City: Kareem Hunt, RB
No question who had to be KC's prove-it player. Hunt had a record 246-yard debut and exploded through the New England defense with five broken tackles. Another big game against a good Eagles defense would say a ton about Hunt's future.
Browns at Ravens
Cleveland: Kenny Britt, WR
The Browns signed Britt to a $32.5 million deal to be a leader among their young offensive players, which is why Hue Jackson called it "inexcusable" that Britt dropped a key fourth-quarter pass in Week 1. Britt caught just one of three targets for 13 yards, giving him fewer targets than teammates Corey Coleman, Seth Devalve and Duke Johnson. That's not a No. 1, which is what he needs to start playing like.
Baltimore: Brandon Carr, CB
Terrell Suggs praised GM Ozzie Newsome for revamping the secondary with Carr, Tony Jefferson and Marlon Humphrey over the offseason, leading to the four-pick day on Dalton in Week 1. Carr had only one interception over the previous three seasons, but he's already got one as a Raven, as well as two passes defended. What can he do against DeShone Kizer?
Bills at Panthers
Buffalo: Mike Tolbert, FB
Despite a change at head coach, the Bills started off this season similar to how they finished last season: As the No. 1 rushing team in the NFL. LeSean McCoy had his regular 22 carries for 110 yards, but Tolbert chimed in a surprising 12 carries of his own, which resulted in 42 yards and a score. It'll be interesting to see how the 32-year-old's season turns out, as he hasn't had that many carries in a game since 2013.
Carolina: Kelvin Benjamin, WR
To become a legitimate No. 1 threat, Benjamin needed to improve his catch rate, which was barely over 50 percent for his career. In Week 1, he was targeted five times and had just a single reception. Averaging 25 yards per catch is good, but averaging five yards per target is terrible.
Cardinals at Colts
Arizona: Justin Bethel, CB
We know there are questions that must be answered at quarterback and running back, but the Cards are still a team whose identity of success is on the back of its defense. Bethel got off to a great start -- an 82-yard interception return for a touchdown to give Arizona a lead -- but his fourth-quarter struggles allowed two touchdowns to Kenny Golladay that gave the Lions a win over the Cardinals. Can he be a true No. 2 next to Patrick Peterson?
Indianapolis: Margus Hunt, DE
It's easy to focus on everything that's going wrong with the Colts, so how about a small (very small) glimmer of hope? Hunt had a sack and two QB hits in Indy's embarrassing 46-9 loss to the Rams -- pretty good for a player who had 1 1/2 sacks over his first four seasons. Can he finally start to find some of that potential?
Titans at Jaguars
Tennessee: Eric Decker, WR
Decker needs to be an important veteran presence for Marcus Mariota, and instead he was awful in his Titans debut, catching three of eight targets for only 10 yards. Barely one yard per target. He must prove he's still a lot better than that.
Jacksonville: Calais Campbell, DL
Debuting in a new city with four sacks must be quite the experience. Campbell is already halfway to his sack total from last season and only 5 1/2 sacks shy of a new career-high. His presence opened up six sacks for teammates also, so even one more sack on Sunday could keep him as the NFL leader through Week 2.
Patriots at Saints
New England: Marcus Cannon, RT
It's easy to focus on a lot that went wrong with the Patriots in their opening loss to the Chiefs. Chris Hogan had eight yards on five targets, Dwayne Allen was nonexistent, Rob Gronkowski didn't play much of a role, Tom Brady didn't have a good start to his age-40 season and the defense allowed 42 points. But the offensive line played well … except for Cannon, who allowed two sacks of Brady in the fourth quarter. Cannon is supposed to be one of the Pats' best players on offense, which is why he got a $32.5 million deal, so he'll have to do better than that this week.
New Orleans: Adrian Peterson, RB
We already knew the defense was going to be bad again, which is why the offense can't have missteps like they had in the running game in Week 1. The Saints' top three backs -- Peterson, Alvin Kamara, Mark Ingram -- carried it 19 times for 53 yards. That's not going to help the Saints upset the Patriots, so they'll need to see Peterson and company prove it was just a one-week slump.
Vikings at Steelers
Minnesota: Sam Bradford, QB
Bradford was too good to believe on Monday night. Literally. I don't believe it can happen again. His 143 passer rating against New Orleans was a career high, as was his 84.3 percent completion rate. I'm not asking him to repeat that performance, but can he even average eight yards per attempt against Pittsburgh?
Pittsburgh: T.J. Watt, LB
Even his older brother J.J. must be jealous of a debut like the one T.J. just had: six tackles, two sacks, one interception, one pass defended. Watt was unstoppable against the Browns, and a repeat performance against Minnesota would set the world on fire over the NFL having two Watts worthy of top-100 consideration.
Bears at Buccaneers
Chicago: Tarik Cohen, RB
With Jordan Howard limited this week with a shoulder injury, it could be integral for the Bears to see Cohen have a performance similar to the one he had in Week 1: five carries for 66 yards, with a 46-yarder in there, plus eight catches for 47 yards and a touchdown. Cohen came from nowhere (fourth-round rookie, actually) to put up 113 total yards. What can he do with a bigger role in the offense?
Tampa Bay: T.J. Ward, S
The Bucs and Dolphins didn't play last week, so they don't quite have the same "prove-it" attitude this week. Instead, Ward has something to prove after being a late cut by the Broncos. It may take time for him to become a full-timer in the Tampa defense, but he's one to watch as the season progresses.
Jets at Raiders
New York: Darron Lee, LB
It's better to focus on what could go right for the Jets, rather than what else could go wrong. Lee had 70 tackles and one sack as a rookie but already has 10 tackles and a sack in 2017. Lee is a talented linebacker who was the 20th overall pick last year. Could he be a breakout star in the absence of Sheldon Richardson this season?
Oakland: Amari Cooper, WR
Cooper could be one of the best receivers in the NFL. He could also be one of the most frustrating. A good bet for at least 1,000 yards every season, Cooper caught just five of 13 targets last week, gaining 62 yards and dropping three passes in a row with Oakland near the end zone. Can he prove to be much more reliable against the Jets and be the elite receiver we know that he can be?
Dolphins at Chargers
Miami: Jay Cutler, QB
As mentioned, the Dolphins don't have a game in their books yet, but they do have a new QB. Cutler clearly has the most to prove, and there's a good chance he'll be no worse than being as effective as Ryan Tannehill. For Miami to get anywhere, though, he may need to be considerably better.
Los Angeles: Keenan Allen, WR
Allen struggled in the Chargers' opening loss to the Broncos, catching five of 10 targets for only 35 yards. Yes, he caught a touchdown. Yes, he's missed 23 games in the past two years. Yes, Denver's pass defense might be the best in the NFL. It's just that 3.5 yards per target and seven yards per catch is very bad. Let's see what he can do in the follow-up.
Cowboys at Broncos
Dallas: Demarcus Lawrence, DE
Lawrence had eight sacks in 2015, then missed most of 2016 and was ineffective when he did get snaps. However, last week he showed up with two sacks as the Cowboys held the Giants to only three points on Sunday Night Football. Dallas could use a highly disruptive defensive end to complement Jaylon Smith, Sean Lee and these young secondary players. Let's find out if it's finally gonna be Lawrence.
Denver: Bradley Roby, CB
There's been some talk for a while that Roby could emerge as the Broncos' best corner at some point, which is high praise, given who Aqib Talib and Chris Harris are. But he came through with an interception against the Chargers (had just five in his first three years) and had two passes defended. Eddie Royal approves.
49ers at Seahawks
San Francisco: DeForest Buckner, DL
Put this on the whole front-seven, but there were a lot of sacks in Week 1 and yet the 49ers had none of them. Not from Buckner, not from Solomon Thomas, not from Arik Armstead or NaVorro Bowman. Zero sacks. That should change against Seattle, but will it be consistent enough and who will lead the charge?
Seattle: Rees Odhiambo, LT
Could it really be this bad for the Seahawks offensive line this season? Despite heavy changes along the NFL's worst line, little improved in Week 1's loss to the Packers, with Russell Wilson under duress on 44 percent of his drop-backs (well above his NFL-high 36 percent pressure rate in 2016) and Seattle unable to move the ball on offense. Odhiambo had a tough task to take over for George Fant just a month ago, but the season is here and excuses are worth as much as a handful of sand from the beach.
Washington at Rams
Washington: Kirk Cousins, QB
I doubt Cousins should ever have to worry about money again, but he could be playing for over $100 million this year. Which is insane when you stop to really think about it. His first test against the Eagles did not go well. The Rams are a middle-ground test, which means Cousins should play a lot better than he did in Week 1 if he wants to stay on the path toward becoming a nine-figure QB.
Los Angeles: Jared Goff, QB
It had to be Goff. He's the "Prove-It Player of the Week," if you will. Goff was historically awful in 2016, but he averaged 10.6 yards/attempt in Week 1 and dominated a horrible Colts defense in the Rams' 46-9 win. Washington's defense is not special, so it'll be interesting to see Goff can continue to play like a former top pick.
Packers at Falcons
Green Bay: Mike Daniels, DT
People may know a little about Daniels, but as a zero-time Pro Bowler, most probably don't know enough. Daniels was unblockable by the Seattle O-line (in a way that is still impressive despite his opponents) and he could start a perennial Pro Bowl run beginning this year.
Atlanta: Austin Hooper, TE
Yes, 88 of Hooper's 128 yards came on a single catch, but the other 40 yards also came on a single catch. He was considered a breakout player before the year started. and the idea of Hooper being a 1,000-yard tight end looks more and more real every week.
Lions at Giants
Detroit: Kenny Golladay, WR
Bethel may have given up the touchdowns, but to his credit, holy crap Kenny Golladay who are you? Let's see what he has in store for Monday Night Football against maybe the best defense in the NFL.
New York: Odell Beckham Jr., WR
To play or not to play? Beckham must have been quite upset to see his offense put up just three points without him, but what else should any of us expect at this point? Eli Manning isn't the type of QB to get it done without a star receiver like Beckham. Brandon Marshall may not have anything left. Evan Engram is just a rookie. The running backs are not good enough to start on most teams. Beckham doesn't need to prove anything more than he is healthy, and if he can't, the Giants might fall to 0-2 without much of a fight.
