When he sees a target -- or more likely, a receiver who will come open -- he has a quick release, plenty of arm strength and good ball placement. He has a chance to have a huge year.
3 Marqise Lee, WR, USC
That USC had several good weapons in the passing game last season didn't stop defenses from paying extra attention to Lee, but it didn't matter. He has the ability to separate with speed and as an effective route-runner. He's dropped a few easy ones, but makes most routine catches and can play bigger than his size. Dangerous after the catch. He's also physical and could've been a top safety if he'd chosen that direction.
4 Cyrus Kouandjio, LT, Alabama
A natural pass-protector with quick feet, long arms and the ability to sit down and absorb rushers, Kouandjio held down the left side of a dominant Alabama offensive line in 2012. He's only going to get stronger, which makes his future exceedingly bright. Could be drafted before he turns 21.
7 Louis Nix III, DT, Notre Dame
One of those players with the rare size and skills to handle a zero-technique role, Nix can keep multiple blockers occupied and make life easy for linebackers cleaning up against the run. Well-liked and reliable, he should be the anchor of what will be the strength of the 2013 Irish squad.
10 Loucheiz Purifoy, CB, Florida
An exceptional athlete, Purifoy also provides value as a returner. He has the ball skills of a wide receiver and could also see time there in 2013. Can get beat because he's still finding his way in terms of technique, but more seasoning could make him a star.
12 Adrian Hubbard, OLB, Alabama
Quietly, Hubbard was the most productive pass-rusher for the Tide in 2012. He led the team in both sacks and tackles for loss. He has the perfect frame to be a 3-4 OLB at the next level, with the ability to set the edge as a strong run defender and turn the corner as a pass-rusher.
15 Timmy Jernigan, DT, Florida State
He arrived in Tallahassee with the frame of a 4-3 defensive end, and the athleticism to play the position, but Jernigan has added the bulk to move inside, where his burst and ability to chase down runners has made him a disruptive interior force. His future is that of a penetrating 4-3 defensive tackle.
16 Sammy Watkins, WR, Clemson
Even as a highly-rated prospect, 2013 represents an opportunity for Watkins to bounce back and show that he's taken the developmental steps necessary to be a true No. 1 wide receiver. His production fell off in 2012, and recent Houston pick DeAndre Hopkins was the more potent threat for Clemson. But Watkins has a ton of natural ability.
17 C.J. Mosley, LB, Alabama
A gifted linebacker in terms of his ability to cover, Mosley has the all-around versatility that will make him an appealing linebacker in any scheme. He flies to the ball and makes a ton of plays; now he simply needs to get a bit stronger and show the leverage against the run, along with the ability to take on blockers and hold his ground.
18 Mike Evans, WR, Texas A&M
At 6-foot-5, Evans sometimes looks like he plays even taller. He simply overwhelms cornerbacks with size, and is a great deep threat even when he doesn't get separation. Evans is also underrated as a receiver who can make defenders miss with the ball in his hands. Even with a redshirt year, he's still learning the position as a late arrival to football, so expect him to get even better in 2013.
19 Cameron Erving, LT, Florida State
Evaluators I've spoken to are extremely high on Erving's potential, and the tape shows why. He moves so easily, and really solidified the left tackle position for the Seminoles last year, even as he continues to figure things out. I wouldn't be surprised if he challenges to be the top tackle in the draft class.
21 Tajh Boyd, QB, Clemson
Of the quarterbacks on the Big Board, Boyd has the best arm strength, and he can make the big throws both down the field and to the edges. He's got plenty of mobility and can escape the rush and throw well on the move. A hard worker who took another step forward with accuracy in 2012, Boyd needs to be smart in his decision-making -- he occasionally forces throws. He's not tall, but otherwise he has all the physical tools you want.
25 Johnny Manziel, QB, Texas A&M
It's amazing to think that at this point a year ago, there was no certainty that Manziel would be the starting QB for the Aggies in 2012. A gifted improviser in the pocket, Manziel has an ability to extend plays that makes you think of Aaron Rodgers. He utilizes great movement skills and vision to overcome a lack of height, and while he doesn't have a big arm, there's no reason to think he won't continue to build arm strength. He's going to get even better.
