I don't think his speed will matter too much in the 40.

He plays the game fast and I think the agility drills are more important at his position.

2nd round seems like a lock at this point, from everything I have read. I think if he can tip the scales at 200, have a respectable bench press, get what's expected of him in the 40, and do well in the agility drills he will launch into that 31 area. (I've heard the Chiefs and Broncos are big fans)

He's not going to get any taller, but I think adding some weight will help him. His coverage skills and special teams plays speaks for itself via film. His cross-positional skills and special teams play are really going to help him get picked before the other safeties outside of Clinton-Dix and Pryor.
