I've seen him play. He has a very weak upper body, and gets easily bull rushed. His technique is poor, but can be worked on. IMO he's not the type of lineman that's going to be able to play right away. He's going to need work, but the ability is there. Think of D. Bell at a bigger program. Although, IMO, I think Bell has more raw talent.
If he gets drafted, gets into a camp, and really does some work (wight lifting and technique wise) I think he could come in and play right away, but I wouldn't bet on it.
