After the combine some players had increase their value. Now we can see the performance of the top 25.
1. Andrew Luck, QB, Stanford (1)
Believe it or not, Luck  actually surprised scouts at the combine by running faster and jumping  higher than most expected. He went a long way toward fully cementing his  status as the top pick in the draft.
2. Robert Griffin III, QB, Baylor (3)
No  one was surprised when Griffin posted a blazing 4.41 40 in  Indianapolis, but scouts were struck by his self confidence and poise.  He has the ability to be a very special player in this league.
3. Matt Kalil, OT, USC (2)
It's hard to imagine a player who  weighs 306 pounds looking thin, but Kalil is built like a 260-pound  tight end. He has an impressive frame and could still add weight.
4. Quinton Coples, DE, North Carolina (4)
Coples is an  extremely athletic player, but it's his strength that opened some eyes  after his performance on the bench press (25 reps).
5. Morris Claiborne, CB, LSU (5)
Claiborne  has long arms and has a very smooth all-around game. He didn't run as  fast as scouts expected, but he still has the ability to turn and run  with NFL receivers.
6. Trent Richardson, RB, Alabama (6)
Recent  surgery prevented Richardson from working out, but his skill set still  makes him highly coveted. He's a compact back with good hands and solid  pass-protection ability.
7. Ryan Tannehill, QB, Texas A&M (7)
After  spending his high school career averaging just 10 pass attempts per  game and only starting one full season at Texas A&M, Tannehill's  learning curve might be steeper than most other QBs in the draft. Don't  be fooled, though -- he has plenty of ability.
8. Riley Reiff, OT, Iowa (8)
At  313 pounds, Reiff is a mobile lineman with good speed and athleticism.  He's also a pretty tough guy, which could stem in part from an  outstanding career as a high school wrestler.
9. Dre Kirkpatrick, CB, Alabama (17)
Kirkpatrick's arms  might not be as long as some other CBs in the draft at 30 5/8 inches,  but he has very good coverage skills and his height (6-foot-2) makes him  hard to throw over.
10. Melvin Ingram, DE, South Carolina (11)
Ingram  significantly improved his stock by staying in school another year. He  also helped himself with his quickness and athleticism. In linebacker  drills, his break on the ball was almost like that of a wide receiver.
11. Luke Kuechly, LB, Boston College (12)
Kuechly's  outstanding recognition -- something that can't be taught -- helped him  make a ton of tackles in college. He has good upper-body strength,  posting 27 reps in the bench press.
12. Justin Blackmon, WR, Oklahoma State (13)
A  tweaked hamstring stopped Blackmon from running at the combine, but he  still displayed great hands and the strength to get inside on slant  routes. If he runs well at his pro day, his stock should go up.
13. Dontari Poe, DT, Memphis (51)
Everyone  marveled at the 346-pounder's time in the 40 (4.98), and he has the  ability to be an All-Pro for years in the NFL. But first he needs to  silence the critics who say he doesn't go hard on every play.
14. David DeCastro, OG, Stanford (14)
DeCastro  looks like a prototypical interior lineman. With good strength and an  ability to pull from the guard spot, he has reminded some of stalwart  Vikings and Seahwaks guard 
Steve Hutchinson.
15. Janoris Jenkins, CB, North Alabama (15)
Off-field issues  aside, Jenkins might be the smoothest of the top DB prospects. He has  good speed and long arms for a player of his size (5-10).
16. Michael Floyd, WR, Notre Dame (19)
Floyd exceeded expectations with a 4.47 in the 40. He also showed better-than-expected hands in the WR drills.
17. Courtney Upshaw, LB, Alabama (9)
Upshaw left  Indianapolis as an enigma. Will he fit better as an outside linebacker  or defensive end? Either way, he'll need to run well at his pro day if  he wants to move up draft boards.
18. Zach Brown, OLB, North Carolina (23)
Brown  is a tremendous athlete who posted an amazing 40 time (4.50) for a  244-pound specimen. His ability to make plays in space should make him a  hot commodity in the draft.
19. Devon Still, DT, Penn State (20)
While  Still didn't run as fast as some might have liked (5.08 40), his  strength and his long arms could make him a good interior lineman.
20. Jonathan Martin, OT, Stanford (18)
Martin  is a technically sound offensive lineman. But he's also looked at as a  finesse player and some scouts would like to see him be more aggressive  at the next level.
21. Michael Brockers, DT, LSU (10)
Brockers  has very good upper-body strength and although he ran a relatively slow  40 (5.36), he fits the mold of a prototypical DL and could be a solid  pass rusher.
22. Rueben Randle, WR, LSU (20)
Randle has  sleeper potential in the draft. He was a big-play guy in college, reads  the ball well and displayed tremendous hands in Indy.
23. Cordy Glenn, OL, Georgia (29)
Glenn is in better shape  than he appeared at the combine. He's light on feet, has good movement  and could earn a chance to play left tackle in the NFL.
24. Nick Perry, DE, USC (25)
Perry projects as a solid NFL  pass rusher who is more suited to play with his hand on the ground. He  is quick with a good first step and above-average strength.
25. Fletcher Cox, DT, Mississippi State (30)
Cox  is a very good athlete who brings a good effort on every play. He  doesn't project as an every down player, but can be a steady pass  rusher. at
