I'm going to get killed for this, and don't get me wrong, I love the momentum and bringing in ATH's from big HS programs... But... I'm not as high on him as some might be, especially at RB.
He may do great, and I've been wrong many times before, I think he's got a ceiling though. A kid who's already worked very hard towards reaching his potential.
The good thing is he can play about 10 different positions on the field.
I'm not saying he's not a good prospect, just saying I think others may have higher ceilings.
