The bigger concern to me is maturity. Not necessarily a problem in the long-run but when you’re talking about ability to a different part of the country, transition to college life/freedom, AND eat some humble pie on the gridiron – that’s a lot for some kids to handle. It is likely to take time.
Mattison will sort out the performance and talent issues, I have no doubt, in the long run. It’s up to the kid to do the things he has to do to take advantage of the opportunity.
