Cardale Jones, QB, Ohio State
There's no denying Cardale Jones' rare blend of size, athleticism and arm strength, but the 6'5", 253-pounder is as raw as they come in terms of quarterback prospects in this year's draft. His physical tools could get him drafted on Day 2, but he'll have to end up in the right system with time to develop in order to reach his potential.
Andrew Billings, DT, Baylor
Andrew Billings flashes dominant power and explosiveness on film, but he's incredibly inconsistent when it comes to finding the ball and maximizing that athleticism. His strong pro-day performance will likely cement his first-round status, but his lack of polish could get exposed at the next level.
Christian Hackenberg, QB, Penn State
One of the most polarizing prospects in the entire draft class, NFL teams might not be sure which version of Christian Hackenberg is the real one. After a promising freshman campaign in Happy Valley, Hackenberg struggled under new head coach James Franklin, but he has the physical makeup of an NFL passer.
Eli Apple, CB, Ohio State
With the increase in big, athletic receivers in the NFL, defensive coaches love corners with size and athleticism who can match up well. Eli Apple fits the bill at 6'1", 199 pounds, but the redshirt sophomore is still fairly raw as far as the finer points of playing the position are concerned. He could easily crack the first round, but he may struggle if thrown to the fire early.
Leonard Floyd, OLB, Georgia
A bit of a tweener prospect, Leonard Floyd added some bulk prior to the combine, where he measured in at 6'6", 244 pounds—13 pounds heavier than his listed weight at Georgia. He's explosive and versatile, but will he retain that explosiveness with the added weight once he puts the pads on this fall? He could go in the first round, but he may struggle to find a position that fits at the next level.
