I don't know, from what I've seen, he's smart, hard working, has good speed, amazing balance, and a lot of toughness. He has tons of yards after contact, and has broken long TD runs in pretty much every game, except against UNLV. I think those attributes will make him a very good NFL running back. Some of it will obviously depend on where he ends up, but IMO, you don't have to be a super freak of an athlete to be an NFL RB. Sure, it helps, but if you can read defenses, be patient in waiting for the line to open up a hole, and take advantages of what the defense gives you, he will be successful.
