2015 NFL Draft Big Board: 21-30

21. Tyler Lockett WR 5'11 175 Kansas State Senior

- Lockett is the most underrated receiver in the country. He could make a solid slot receiver in the league. An excellent technician at the position. He's basically KSU's entire passing offense at times throughout his career. A third generation Wildcat, amazingly all three were coached by Bill Snyder. NFL Comp: Wes Welker

Previous Ranking: 82

22. Denzel Perryman ILB 5'11 240 Miami (FL) Senior

- Perryman is one of the best inside linebackers in this class. He's a big hitter with a nose for the football. A good athlete that can cover fleet footed slot receivers and is almost impossible to block due to his instincts and strength. He also has the talent to play outside 'backer as well but is better suited inside. NFL Comp: Thomas Davis

Previous Ranking: 28

23. La'el Collins OT 6'5 315 LSU Senior

- Collins shocked everyone by electing to stay in school in 2014 (he would've been a Day 2 selection had he gone pro). A rock for the Tigers who were shaky at times on offense that had multiple QB issues. NFL Comp: Michael Roos

Previous Ranking: 25

24. Eric Kendricks ILB 6'0 228 UCLA RS Senior

- Kendricks had a great 2014 showing as a redshirt senior. Jordan Zumwalt who? He's nipping at the heels of Perryman for the honor of second best inside linebacker. NFL bloodlines as Mychal Kendricks is his older brother. NFL comp: NaVarro Bowman

Previous Ranking: 55

25. Jameis Winston QB 6'3 230 Florida State RS Sophomore

- The 2013 Heisman winner had an uneven 2014 to say the least. He has been below average in the first half of games (something like 20 interceptions including a whopping three in the first QUARTER against Florida) and on fire in the second as the Noles frequently had to storm back and win games late. Winston has off the field issues, yes but I won't go into those as they have been discussed a lot and my opinion on the matter has been stated. He's the most pro ready QB in the class as FSU runs a pro style system. NFL Comp: Big Ben

Previous Ranking: 11

26. Ifo Ekpre-Olomu CB 5'10 185 Oregon Senior

- Was inconsistent in 2014 due to injury. When healthy, he's one of the best corners in the country. Had a great highlight reel interception in the Michigan State game. NFL Comp: Alterraun Verner

Previous Ranking: 8

27. Ameer Abdullah RB 5'9 190 Nebraska Senior

- Abdullah was a Heisman candidate until he injured his knee late in the year. A bowling ball type of runner who was the Huskers only offense at times. NFL comp: MJD

Previous Ranking: 88

28. Brandon Scherff OT 6'5 315 Iowa RS Senior

- A road grader type as a tackle and is one of the best linemen in Hawkeyes history. NFL comp: David Stewart

Previous Ranking: 19

29. Nick O'Leary TE 6'3 248 Florida State Senior

- The best tight end in the country and has the Mackey Award to prove it. In his spare time, he likes to take on city buses in a game of chicken and beat them. Grandson of legendary golfer Jack Nicklaus. NFL Comp: Gronk

Previous Ranking: 22

30. DeVante Parker WR 6'3 210 Louisville Senior

- Battling Kevin White for the second best receiver title. Did not play in the Cardinals' first seven games due to a broken foot but still managed to post over 700 yards and 5 touchdowns. Absolutely blew up against FSU's secondary to the tune of 8 catches for 214 yards in only his second game back. NFL Comp: Roddy White

Previous Ranking: 62
