It is officially game week.

This weekend and next, 128 FBS teams will make their 2015 college football debuts, hoping to translate the optimism of the offseason into actual on-field success during the fall. Obviously, that success won't actually happen for a large portion of the college football landscape.

But the preseason is supposed to be a time for optimism, and if you look hard, there's something to be positive about for every team. So, in that spirit, our preseason college football rankings count down every team from 128 to 1, while also offering something nice about everyone.

For more extensive previews of every team, check out the Sports on Earth conference preview series, along with the rest of our preseason content.

128. Charlotte. Two years ago, the 49ers played their first football game since 1948. Now they're about to play their first major college football schedule ever.

127. Georgia State. The Panthers may have gone 1-11 in their second season of FBS play, but they lost three games by a field goal. They're getting better.

126. Eastern Michigan. Quarterback Reginald Bell is one of the Eagles' most intriguing players in years and could become a MAC star.

125. UTSA. Lots of new faces for a young team that lost most of its starters, but transfers from Michigan, Oklahoma, Baylor and Illinois provide intrigue.

124. UNLV. The Rebels made a smart gamble by hiring Tony Sanchez, coach of nearby high school powerhouse Bishop Gorman in Las Vegas.

123. New Mexico State. Tailback Larry Rose had four games of 137-plus rushing yards in his last five games as a freshman.

122. Idaho. Top receiver Dezmon Epps, who caught 77 passes for 971 yards in 2013, returns from a season-long dismissal from the team to enliven the passing game.

121. Miami (Ohio). It's a long road back to relevance, but Chuck Martin was a prudent hire who can turn the RedHawks around.

120. Troy. New head coach Neal Brown, who favors an up-tempo style, was the offensive coordinator for back-to-back Sun Belt champion Troy teams in 2008-09.

119. Kent State. The top 11 tacklers return to the Golden Flashes defense, including All-MAC safety Nate Holley, who had 137 tackles as a sophomore.

118. North Texas. Special teams matter too: Mean Green kicker Trevor Moore hit 15 of 17 field goals as a freshman, punter Eric Keena averaged 44.8 yards per attempt and their kick returners ranked 20th nationally.

117. Army. In his first season on the field, linebacker Jeremy Timpf had 14 ½ tackles for loss, 117 tackles and three interceptions, pushing him to a team captaincy as a junior this fall.

116. SMU. It won't take long for new coach Chad Morris -- with his enthusiasm, proven track record as an offensive coach and deep ties to the region -- to make Mustangs fans start forgetting about 2014.

115. Hawaii. USC transfer quarterback Max Wittek can spark a turnaround for an offense that returns a lot of experience.

114. Central Michigan. Quarterback Cooper Rush ranked 17th in passer rating in 2014, throwing for 3,157 yards and 27 touchdowns with an average of 8.3 yards per attempt.

113. South Alabama. It took only six years of football existence for South Alabama to go to a bowl game, and now the arrival of several UAB transfers will ease the pain of losing a lot of senior starters.

112. Southern Miss. An influx of talent via transfers could see Todd Monken pull Southern Miss out of its stunning three-year nosedive.

111. Florida International. Few tight ends are as dynamic as Jonnu Smith, who caught 61 passes for 710 yards and eight touchdowns as a sophomore.

110. Massachusetts. Mark Whipple quickly gave the Minutemen a potent offense, and they return 10 starters -- including pro prospects in quarterback Blake Frohnapfel and receiver Tajae Sharpe.

109. Buffalo. The Bulls made an intriguing coaching hire by bringing in Lance Leipold, who went 109-6 with six Division III national championships at Wisconsin-Whitewater.

108. San Jose State. The Spartans' latest recruiting class ranked 58th in the 247Sports composite rankings, ahead of Iowa, Oregon State, Pitt, Boston College and Minnesota, among other Power Five schools.

107. Louisiana-Monroe. Despite playing nose tackle, Missouri transfer Gerrand Johnson led the Warhawks with 92 tackles and had 12 ½ tackles for loss.

106. Texas State. The Bobcats got left out of the postseason despite a 7-5 record last season. With eight starters back on offense, Dennis Franchione's Bobcats have a chance to correct that.

105. Connecticut. The idea of the Civil Conflict rivalry with UCF is so ridiculous that it just may work.

104. Tulsa. With former Baylor offensive coordinator Philip Montgomery inheriting an experienced offense that was relatively productive last year -- led by receiver Keevan Lucas -- the Golden Hurricane will score plenty of points.

103. Kansas. New coach David Beaty understands the challenges of this job and is focused on trying to build a program without shortcuts, so he's already an improvement over Charlie Weis.

102. Ohio. The Bobcats have finished at least .500 in six straight seasons, with Frank Solich owning a 72-56 record in Athens. Ohio hadn't played in a bowl game since 1968 until he arrived.

101. Wyoming. Coach Craig Bohl took North Dakota State from Division II to three straight FCS championships in a decade. The Cowboys are bound to be on an upward trajectory shortly.

100. Akron. Led by linebacker Jatavis Brown, the Zips led the MAC in scoring defense and yards per play allowed in 2014.

99. Florida Atlantic. As a juco transfer, quarterback Jaquez Johnson threw for 2,215 yards, 17 touchdowns and five picks and ran for 513 yards and seven touchdowns.

98. Old Dominion. The Monarchs scored 32.7 points per game in their first full-time FBS season, with running back Ray Lawry averaging 7.1 yards per carry and scoring 16 touchdowns.

97. Tulane. Cornerback Parry Nickerson intercepted six passes as a freshman, and 5-foot-9 linebacker Nick Marley has 24 ½ tackles for loss in two seasons.

96. Ball State. Despite going 5-7 last year, Pete Lembo is 30-20 at Ball State, which is no small feat, and he returns an experienced team.

95. New Mexico. Bob Davie's option offense racked up 310 rushing yards per game, with Jhurell Pressley averaging 9.5 yards per rush on 114 attempts. The Lobos even scored 49 points against Boise State in a losing effort.

94. South Florida. A sluggish offense can build around tailback Marlon Mack, who ran for 1,041 yards as a true freshman.

93. Fresno State. The Bulldogs are known for passing, but tailback Marteze Waller averaged 6.1 yards per carry last year, rushing for 1,368 yards and 11 touchdowns

92. Nevada. Senior defensive end Ian Seau, the nephew of Junior Seau, is coming off a junior season in which he had 8 ½ sacks.

91. Louisiana-Lafayette. The Ragin' Cajuns have won nine games four years in a row, and they have the Sun Belt's Reggie Bush in Elijah McGuire, who averaged 7.6 yards per carry and caught 45 passes for 468 yards as a sophomore.

90. Rice. Owls quarterback Driphus Jackson threw for 2,842 yards and 24 touchdowns and ran for 401 yards as a junior.

89. Middle Tennessee. Senior safety Kevin Byard has intercepted 15 passes in his career, returning four of them for touchdowns.

88. UTEP. Sean Kugler is making power football work at his alma mater. Aaron Jones ran 242 times for 1,3274 yards and 11 touchdowns and caught 30 passes for 293 yards and three touchdowns in 2014.

87. Wake Forest. The running game can only get better, and the Demon Deacons do have a reliable weapon in sophomore tight end Cam Serigne, who caught 54 passes as a freshman.

86. Appalachian State. In their first FBS season, the Mountaineers finished on a six-game winning streak, and they return nearly every starter.

85. Vanderbilt. Derek Mason is wisely taking over defensive play-calling, and he gets nearly the entire defense back.

84. East Carolina. Uncertainty at quarterback will be eased by a possible breakout by senior running back Chris Hairston (6.7 yards per carry) behind a sturdy offensive line.

83. Syracuse. The Orange can't possibly have the same bad injury luck as last year, and the return of quarterback Terrel Hunt will breathe some life into the offense.

82. Purdue. Kicker Paul Griggs went 16-of-20 on field goals, making all three from 50 yards or longer, which helps in close games. Purdue has at least improved enough to make more games close.

81. Georgia Southern. The Eagles won the Sun Belt in their first FBS season, and they led the nation in rushing by averaging 380 yards per game. Thousand-yard rushers Matt Breida and Kevin Ellison are back, although Ellison must serve a two-game suspension.

80. Arkansas State. All of the Red Wolves' backs and receivers return, with Fredi Knighten coming off a season in which he threw for 3,277 yards and 24 touchdowns and ran for 779 yards and 11 touchdowns.

79. Colorado State. Mike Bobo inherits an offense that loses star quarterback Garrett Grayson, but at least he'll have one of the nation's best receivers in Rashard Higgins, who caught 96 passes for 1,750 yards and 17 touchdowns as a sophomore.

78. Bowling Green. Dino Babers' offense gets back star quarterback Matt Johnson, who missed last year with a hip injury but threw for 3,467 yards and 25 touchdowns for the 2013 MAC champions before Babers arrived.

77. Louisiana Tech. Safety Xavier Woods returned six interceptions for 230 yards last year, and senior running back Kenneth Dixon has scored 61 total touchdowns in his career.

76. Iowa State. Allen Lazard, D'Vario Montgomery and Quenton Bundrage give the Cyclones a potentially dangerous receiving corps.

75. Colorado. With a 13-game schedule, Nelson Spruce may lead the nation in catches after posting 106 for 1,98 yards in 12 games in 2014.

74. Illinois. The Fighting Illini could actually improve by pushing Tim Beckman out and letting offensive coordinator Bill Cubit call the shots this year.

73. Western Michigan. The Broncos jumped from 1-11 to 8-5 in P.J. Fleck's second season and return the entire core of productive offense, including quarterback Zach Terrell, running back Jarvion Franklin and receiver Corey Davis, each of whom earned All-MAC honors.

72. Oregon State. The transition to a freshman quarterback under a new coaching staff is made easier by the return of tailback Storm Barrs-Woods (6.3 yards per carry) and receiver Victor Bolden (72 catches).

71. Northern Illinois. The Huskies are an absurd 57-13 in their last five seasons under three coaches, winning their division five straight times and the MAC title three times.

70. Temple. The Owls return 10 starters to a defense that ranked fourth nationally in scoring defense and 11th in yards per play allowed.

69. Air Force. Brilliantly named safety Weston Steelhammer earned first-team All-Mountain West honors with 61 tackles, three sacks and six interceptions.

68. Marshall. A 244-pound converted tight end, Devon Johnson is coming off a move to running back that resulted in 206 carries for 1,767 yards (8.6 per carry) and 17 touchdowns.

67. Indiana. UAB transfer Jordan Howard, an All-Conference USA runner, will ease the pain of losing 2,000-yard rusher Tevin Coleman, and the offense as a whole gets a boost from the return of quarterback Nate Sudfeld from injury, behind an underrated line.

66. Maryland. Junior cornerback William Likely does it all for the Terrapins, making 83 tackles, interceptions six passes, averaging 11.2 yards per punt return and averaging 31 yards per kick return. He also had four total return touchdowns.

65. San Diego State. Winning by playing defense and relying heavily on the ground game can work when a tailback like Donnell Pumphrey runs for 1,867 yards and 20 touchdowns.

64. Toledo. There are few more dynamic runners than Kareem Hunt, who ran for 1,631 yards (8.0 yards per carry) and 16 touchdowns in only 10 games. However, again Hunt will have to deal with a shortened schedule, as he has been suspended for the Rockets' first two games.

63. Utah State. Star quarterback Chuckie Keeton is back after missing most of the last two seasons with injuries, and the defense has been good enough to help push the Aggies to 30 wins in three seasons.

62. Western Kentucky. The Hilltoppers finished sixth in scoring, and they get back quarterback Brandon Doughty, who threw for 4,830 yards and 49 touchdowns.

61. Washington State. New quarterback Luke Falk looked solid upon taking over for an injured Connor Halliday as a freshman, so Mike Leach's offense will give Wazzu a chance to get back to a bowl game.

60. Navy. Quarterback Keenan Reynolds has 64 career rushing touchdowns, which means he's 14 away from breaking Montee Ball's all-time FBS record.

59. Northwestern. Running back Justin Jackson ran for 1,187 yards and 10 touchdowns as a true freshman, giving the Wildcats a reliable tailback with an uncertain quarterback situation.

58. Washington. Sophomore safety Budda Baker is already a defensive star after posting 80 tackles, and now the Huskies may put his athleticism to use on offense too.

57. UCF. Thomas Niles leads an athletic, deep defensive line that led a defense that finished fourth in yards per play allowed in 2014.

56. Houston. The Cougars might have made the best hire of the coaching carousel by landing Ohio State offensive coordinator Tom Herman as their new head coach.

55. Virginia. Even without Eli Harold and Anthony Harris, Virginia will field a feisty defense led by safety Quin Blanding, who led the team with 123 tackles as a true freshman.

54. Rutgers. LSU transfer Hayden Rettig is in decent position to succeed with a strong supporting cast led by All-Big Ten receiver Leonte Carroo and a deep backfield that gets Paul James back from a torn ACL.

53. Boston College. The Eagles ranked second nationally in run defense last year and return most of their defensive line rotation plus their top two tacklers.

52. Duke. Good luck finding a better safety tandem than Jeremy Cash and DeVon Edwards. They combined for 244 tackles last season, with Cash recording 10 ½ tackles for loss, four forced fumbles and two picks and Edwards recording 7 ½ tackles for loss, five forced fumbles and nine pass breakups.

51. Kentucky. Patrick Towles is a promising talent at quarterback, and he could lead the Wildcats to their first bowl since 2010 and first win over Florida since 1986.

50. Iowa. Senior defensive end Drew Ott had 7 ½ sacks and 12 tackles for loss last season, then went to Big Ten media days and ate a raw egg on camera.

49. Kansas State. Expectations are relatively low for Kansas State, which means that Bill Snyder will probably pull off another magic trick and 1) ruin a playoff contender's season and/or 2) win 10 games.

48. Memphis. The Tigers held onto heralded coach Justin Fuente after a 10-3 season, and they also get back junior quarterback Paxton Lynch, who threw for 3,031 yards and 22 touchdowns and ran for 13 touchdowns for the AAC co-champions.

47. Miami. The Hurricanes found an All-ACC caliber quarterback last year in Brad Kaaya, who threw for 3,198 yards and 26 touchdowns as a true freshman.

46. North Carolina. The Tar Heels have the making of a potent offense behind quarterback Marquise Williams (3,068 passing yards, 788 rushing yards, 34 total touchdowns) and a talented offensive line.

45. Florida. Few teams are tougher to throw on than the Gators, who pair a solid pass rush with one of the nation's top defensive backfields, led by All-American cornerback Vernon Hargreaves.

44. California. The Golden Bears should be able to score on anyone with their Air Raid offense, with impressive skill position talent and a future NFL quarterback in Jared Goff, who came up just shy of 4,000 yards as a sophomore.

43. N.C. State. Florida transfer Jacoby Brissett made it clear that the Gators shouldn't have let him get away in a solid debut season in which he had 2,605 yards, 23 touchdowns and five picks passing and 529 yards and three touchdowns rushing.

42. Pittsburgh. The Panthers' one-two punch at running back and receiver is hard to beat: James Conner ran 298 times for 1,765 yards and 26 touchdowns, and Tyler Boyd caught 78 passes for 1,261 yards and eight touchdowns.

41. Texas. The biggest impact from a true freshman this season might come from linebacker Malik Jefferson stepping into Charlie Strong's defense.

40. Texas Tech. Kliff Kingsbury's version of the Air Raid should be alive and well behind Jakeem Grant, DeAndre Washington and either quarterback, whether it's Patrick Mahomes or Davis Webb.

39. BYU. Star quarterback Taysom Hill returns from a season-ending injury and will get a chance to shine on a big stage against Nebraska, Boise State, UCLA and Michigan in September.

38. Michigan. You may have heard that Jim Harbaugh is now coaching the Wolverines. 

37. South Carolina. Pharoh Cooper is one of the best all-around playmakers in the country: He caught 69 passes for 1,136 yards and nine touchdowns. He ran 27 times for 200 yards and two touchdowns. He completed 5 of 8 passes for 78 yards and two touchdowns.

36. Cincinnati. Former five-star recruit Gunner Kiel threw for 3,254 yards and 31 touchdowns in his first season as a starter after transferring from Notre Dame, leading what will be one of the best Group of Five offenses.

35. West Virginia. Defense has gone from liability to strength of the Mountaineers, with Karl Joseph leading the Big 12's best secondary.

34. Minnesota. The Golden Gophers will continue to be tough to throw on with the excellent cornerback combination of Eric Murray and Briean Boddy-Calhoun.

33. Penn State. Hardly anybody moved the ball well on the Nittany Lions last year, and that'll continue with the return of defensive coordinator Bob Shoop and the outstanding tandem of Anthony Zettel and Austin Johnson at tackle.

32. Missouri. The Tigers have won back-to-back SEC East titles and have a favorable enough schedule to compete for the division championship again.

31. Nebraska. Don't let last year's problems in run defense take away from the fact that Nebraska has a fantastic defensive tackle combination in Maliek Collins and Vincent Valentine.

30. Utah. The running/receiving of Devontae Booker and a talented defensive front can keep the Utes competitive in a loaded Pac-12 South.

29. Louisville. The Cardinals will continue to play excellent defense, led by a terrific defensive front that features Sheldon Rankins, James Burgess, Keith Kelsey and TCU/juco transfer Devonte Fields.

28. Mississippi State. Dak Prescott is the best returning quarterback in the SEC after throwing for 3,449 yards and 27 touchdowns and rushing for 986 yards and 14 touchdowns.

27. Oklahoma State. The Cowboys are back on the upswing with a more experienced defense and a possible star at quarterback in sophomore Mason Rudolph.

26. Arizona. Last year, the Wildcats won the Pac-12 South while starting a freshman at both quarterback (Anu Solomon) and running back (Nick Wilson). It doesn't hurt that ultra-productive linebacker Scooby Wright returns too.

25. Arkansas. The Razorbacks have bought into BielemaBall, with a massive offensive line and a bruising running game led by Alex Collins establishing a clear team identity.

24. Wisconsin. New coach Paul Chryst, a former offensive coordinator under Bret Bielema, retained defensive coordinator Dave Aranda, meaning this should be another smooth coaching transition.

23. Georgia Tech. Paul Johnson found a perfect quarterback for his system in Justin Thomas, who led the Yellow Jackets to an ACC Coastal title and dominant Orange Bowl win.

22. Virginia Tech. A great defense is going to be even better thanks to a secondary and pass rush that both rank among the nation's best.

21. Tennessee. Butch Jones finally has the depth and talent to compete for an SEC East title again, with impressive young players like Derek Barnett and Jalen Hurd leading the way.

20. Stanford. The Cardinal offense clicked down the stretch last year and gets most of its pieces back, with Christian McCaffrey capable of bringing life to the running game.

19. Ole Miss. The stars of Ole Miss' recruiting class of 2013 -- Robert Nkemdiche, Tony Conner, Laremy Tunsil and Laquon Treadwell -- are now juniors that have lived up to the hype.

18. Texas A&M. The Aggies passing game is loaded with touted recruits, with Kyle Allen and Kyler Murray throwing to players like Ricky Seals-Jones, Speedy Noil and Christian Kirk.

17. Boise State. Coming off another Fiesta Bowl win, Boise State returns 17 starters, including All-America candidates on defense in safety Darian Thompson and end Kamalei Correa.

16. Florida State. Jimbo Fisher has signed a top-five recruiting class in four of the last five years. "Rebuilding" for Florida State is much more palatable that rebuilding for rivals Miami and Florida right now.

15. Arizona State. The Sun Devils are deeper and more experienced than last year, when they went 10-3. Expect an aggressive, entertaining performance from the defense all season.

14. Michigan State. The Spartans have the foundation of a great team: a senior All-Big Ten quarterback in Connor Cook, one of the nation's best offensive lines and one of the nation's best defensive lines.

13. Oklahoma. New blood on offense can snap Oklahoma out of its funk, with coordinator Lincoln Riley and quarterback Baker Mayfield stepping into a talented unit led by tailback Samaje Perine and receiver Sterling Shepard.

12. UCLA. The Bruins' new quarterback may be a true freshman, but Josh Rosen is a five-star recruit who enrolled early and joins 18 returning starters from a 10-3 team.

11. Auburn. Will Muschamp was the perfect choice to fix Auburn's defense, and we know Gus Malzahn can get the most out of his offense, with a breakout from quarterback Jeremy Johnson likely.

10. LSU. The Tigers were young last season and boasted a ton of rising stars, including tailback Leonard Fournette, safety Jamal Adams and linebacker Kendell Beckwith. Les Miles is still one of the nation's best recruiters.

9. Clemson. Rebuilds along both lines are easier to take when you have a quarterback like Deshaun Watson, who is the most talented player at the position in college football.

8. Notre Dame. The Fighting Irish should be deeper and healthier in 2015, with coveted NFL prospects like linebacker Jaylon Smith and left tackle Ronnie Stanley capable of leading a playoff contender.

7. Oregon. Eastern Washington transfer Vernon Adams is a special talent at quarterback and will be surrounded by a loaded supporting cast in an offense that ranks among the nation's best year after year.

6. TCU. An offense that jumped from 88th to second in scoring gets 10 starters back, including Heisman candidate quarterback Trevone Boykin and standouts at running back (Aaron Green) and receiver (Josh Doctson).

5. Georgia. There is no stopping sophomore tailback Nick Chubb (1,547 yards despite starting only eight games), especially when he's running behind the SEC's best offensive line.

4. USC. The Trojans have playoff-caliber talent, with a proven quarterback in Cody Kessler, who threw for 3,826 yards and 39 touchdowns and multi-dimensional playmakers in stars like Adoree Jackson and Su'a Cravens.

3. Alabama. Five straight No. 1 recruiting classes, according to 247Sports, give Alabama the talent to reload on offense, along with the deepest defensive front in college football.

2. Baylor. The Bears are loaded on both lines and at the skill positions, and new quarterback Seth Russell is all but guaranteed to be a breakout star in the prolific Baylor offense.

1. Ohio State. The national champions lost zero underclassmen early to the NFL draft. They have two All-America candidates at quarterback (J.T. Barrett, Cardale Jones), one at running back (Ezekiel Elliott), two on the offensive line (Taylor Decker, Pat Elflein), two on the defensive line (Joey Bosa, Adolphus Washington), one at linebacker (Darron Lee) and one in the secondary (Vonn Bell) -- with others in the mix at every position. The Buckeyes also have Urban Meyer, who is the best coach in college football.
