7. DI Jerry Tillery, Notre Dame

Tillery tied Quinnen Williams for the highest pass-rushing grade among interior defenders in college football. Tillery's sack totals don't tell the whole story as he was a dominant week in and week out.

8. DI Jeffery Simmons, Mississippi State

He tore his ACL but did it so early in the process that he could still play as a rookie. Simmons had a run-defense and pass-rushing grade over 90.0 this past season.

9. CB Greedy Williams, LSU

His sophomore campaign wasn't quite as dominant as his freshman season, but he still only allowed 27 of his 74 targets to be completed.

10. QB Dwayne Haskins, Ohio State

Haskins certainly improved as the season went on, but his 84.9 passing grade leaves us with some reservations.

11. DI Ed Oliver, Houston

His pass-rushing finally came around with a 90.8 grade this past season, but considering his size and the competition he was facing, he still has a ways to go.

12. LB Devin White, LSU

No linebacker in college football had a higher grade in coverage than White's 91.6 last season. His freakish athleticism suggests it was no fluke.

13. OT Andre Dillard, Washington State

Dillard had the highest pass protection grade of any starting tackle in the country at 94.0 this past season.

14. Edge Brian Burns, Florida State

Burns racked up the most pressures of any Power-5 defender in the country last year with 69.

16. CB Deandre Baker, Georgia

Baker has posted back-to-back 90.0-plus graded seasons in coverage. This past year, he allowed all of 10 first downs all season and no touchdowns.

17. WR D.K. Metcalf, Ole Miss

Metcalf's numbers aren't anything special, but his physical traits and high-end plays are promising.

18. LB Devin Bush, Michigan

Bush can be a weapon as a blitzer in the right scheme. He had top-five pass-rushing grades among off-ball linebackers each of the past two seasons.

19. OT Dalton Risner, Kansas State

Risner started all four seasons at Kansas State and his career low grade was 87.9 overall.

20. WR A.J. Brown, Ole Miss

Brown was the definition of a complete receiver for Ole Miss. He forced 17 broken tackles, had 34 explosive plays and only dropped five passes on 90 catchable.

Hockenson had the second-highest receiving grade among tight ends in college football this past year, dropping one pass on 51 catchable targets.

Arcega-Whiteside led the entire draft class with 19 contested catches this past season on only 32 contested opportunities.

25.DI Christian Wilkins, Clemson

Wilkins was top three in both run-defense and pass-rushing grade among interior players this past season.

26. C Elgton Jenkins, Mississippi State

The Mississippi State center allowed all of five pressures this past season on 369 pass-blocking snaps.

28. S Darnell Savage, Maryland

Savage has back-to-back seasons with grades over 86.0 overall. He's a missile around the line of scrimmage, laying some impressive hits in the flat.

29. Edge Chase Winovich, Michigan

Winovich is coming off back to back seasons with grades over 90 overall – the only such qualifying power-5 player in the draft class that can boast that.

30. WR Andy Isabella, Massachusetts

Isabella was the highest-graded wide receiver in the country, racking up 1,696 yards, including 219 against Georgia.

31. WR Marquise Brown, Oklahoma

Brown was a threat to take it to the house every time he touched the ball. He broke 17 tackles on 77 catches and scored 10 touchdowns.

32. DI Dexter Lawrence, Clemson

Nose tackles of 340-plus pounds are going the way of the Dodo in the NFL, but Lawrence is a pretty ridiculous athlete for his size. He had the 12th best pass-rushing grade among interior players in college football.

33. CB David Long, Michigan

Long allowed all of 18 catches on 595 coverage snaps in his entire college career at Michigan

35. Edge Clelin Ferrell, Clemson

Ferrell racked up 14 sacks and 14 hits on the season and has ideal build to fit in any scheme.

36. CB Amani Oruwariye, Penn State

Oruwariye had the best week of any corner at the Senior Bowl, notching the highest win rate among all defenders in the one-on-ones.

37. QB Drew Lock, Missouri

Lock paired an NCAA leading 33 big-time throws with only six turnover-worthy plays as a senior.

38. S Taylor Rapp, Washington

Rapp was one of the most assignment-sure safeties in the country this past season and missed all of two tackles on 56 attempts.

39. CB Justin Layne, Michigan State

Layne's 89.5 coverage grade last year was ninth best among Power-5 corners in the nation. He also dabbled at receiver where he took 36 snaps this past season.

40. Edge Zach Allen, Boston College

Allen was one of the best run defenders in college football in 2017 before a 90.3 pass-rushing grade this past season. He was an ironman for BC, playing 107 snaps against Wake Forest this past season.

42. WR Hakeem Butler, Iowa State

Butler's size (6-foot-5, 227 pounds) might suggest a possession receiver, but he had more receptions 20-plus yards downfield (19) than anyone in the draft class.

43. TE Noah Fant, Iowa

Fant is the most freakishly athletic tight end in this draft class, but his inconsistent hands are still a concern. He's dropped 11 passes on 80 catchable the past two seasons.

44. S Amani Hooker, Iowa

Hooker's 91.1 coverage grade last season was the second-highest of any defensive back in the country.

45. CB Julian Love, Notre Dame

Love's 21 forced incompletions were the sixth-most in college football last season and his 14 coverage stops ranked 10th.

46. Edge Montez Sweat, Mississippi State

Sweat's 19.1% pressure percentage was top 10 among edge defenders in the draft class and the third highest in the SEC last season.

47. DI Khalen Saunders, Western Illinois

Saunders moves like an edge and even played there at times for Western Illinois. He went to the Senior Bowl and had the second-highest win rate among interior players in the one-on-ones.

48. DI Rashan Gary, Michigan

Gary's production has yet to catch up to his freakish athleticism. He earned a 68.3 pass-rushing grade this past season.
