How did we rank the players?
We asked 43 of ESPN's college football writers, editors and analysts to rate players on a scale of 0-10 based on their expected contributions for the 2015 season.

Full player rankings:
1-10 | 11-20 | 21-30 | 31-40 | 41-50 | 51-60 | 61-70 | 71-80 | 81-90 | 91-100

51. Carl Lawson
Auburn Tigers
Sophomore | Defensive end
Score: 7.23

Lawson missed the 2014 season because of an ACL tear, but the Tigers expect a big impact from the healthy, 6-foot-2, 257-pound defensive end this season. Gus Malzahn noted how much the Tigers missed him a year ago; under new defensive coordinator Will Muschamp, Lawson will be a key piece to what Auburn fans hope is a vastly improved unit.

52. Anthony Zettel
Penn State Nittany Lions
Senior | Defensive tackle
Score: 7.21

When he's not tackling trees, Zettel is finding some other way to impress onlookers with his athleticism. He somehow managed to lead PSU in interceptions (three), tackles for loss (17) and sacks (eight) last season. And he also broke up five passes, which was good enough for third on the Nittany Lions. He's incredibly quick for being 6-4 and 278 pounds, and he can bring a heavy pass rush that few defensive tackles can match.

53. Jared Goff
California Golden Bears
Junior | Quarterback
Score: 7.19

If Cal fielded what amounted to even an average -- or maybe slightly-below-average -- defense during the past two seasons, Goff would be a national name and on just about every preseason Heisman watch list. But it didn't, so he isn't. Without the wins to garner more national attention, Goff quietly put up a remarkable sophomore season (3,973 yards passing, 35 TD, 7 INT, 62.1 completion percentage) and tops Mel Kiper Jr.'s rankings of eligible quarterbacks for the 2016 draft.

54. Sheldon Day
Notre Dame Fighting Irish
Senior | Defensive tackle
Score: 7.14

Named a captain as a junior, Day tallied 7.5 tackles for loss and two forced fumbles in 2014, his first season playing primarily inside after two years at end. The versatility makes him attractive at the next level, but Day, one of the steadiest and most overlooked players on the Irish roster, passed on the NFL for one more year in South Bend.

55. Corey Coleman
Baylor Bears
Junior | Wide receiver
Score: 7.12

Had he not sat out for nonconference play with a hamstring injury, Coleman likely would've ended up with All-America-caliber numbers. His versatility -- Coleman logged 11 carries at running back last year, including one TD -- makes him a difficult asset to contain in the Bears' offense. If he can put up 1,119 receiving yards and 11 scores on only 90 targets in 2014, imagine what Coleman will do as a go-to receiver for Seth Russell.

T-56. Derek Barnett
Tennessee Volunteers
Sophomore | Defensive lineman
Score: 7.09

Barnett wasted no time making an impact in Knoxville, setting Tennessee true freshman records for tackles for loss (20.5) and sacks (10) in a season. The Vols have high hopes in 2015, and a lot of those are pinned on Barnett being even better as a sophomore.

T-56. Pharoh Cooper
South Carolina Gamecocks
Junior | Wide receiver
Score: 7.09

Cooper is listed as a receiver but is an all-purpose threat. The first-team All-SEC pick in 2014 was third in the league in receptions (69), second in receiving yards (1,136) and ninth in all-purpose yards per game (108.5). He's a quality kickoff and punt returner and is poised for another big season.

58. Leonard Floyd
Georgia Bulldogs
Junior | Linebacker
Score: 7.07

The junior linebacker had a team-best six sacks to go with 55 tackles and 8.5 tackles for loss in 12 games a season ago and was voted the Dawgs' defensive MVP. The versatile talent will be an option at both outside linebacker and inside linebacker for Mark Richt this fall.

59. Corey Clement
Wisconsin Badgers
Junior | Running back
Score: 7.05

The time has finally arrived for the junior from New Jersey, who watched as Melvin Gordon ran wild in 2014 and as Gordon teamed with James White in 2013. Clement rushed for 949 yards as a sophomore, showing the speed and power that generate belief he'll be the next star Wisconsin back. He's already a leader for the Badgers, who again will rely on the running game to set the offensive pace.

60. Jalen Mills
LSU Tigers
Senior | Defensive back
Score: 7.02

After bypassing the NFL draft, Mills is back for his senior season. He has more starts under his belt (39) than any LSU defensive player, starting all of those games. The former cornerback has played both safety positions for the Tigers and has 186 tackles and six interceptions in his career.
