I agree with
@Red Five that the book is still out on Ervin. I'd actually lean more towards "I doubt he does anything above average at NU" at this point.
I'd also say that Grant regressed on a personal level as the season wore on and I don't think I can give him too much benefit of the doubt with the line play being that much worse down the stretch. You either fight for yardage or you don't, and for me the eyeball test said he wasn't fighting for yards in the back half like he was in the first half.
Hoping Allen is a standout mainly because he's a young guy and could really stand out by the time he's a junior.
