To me, regardless of what the advisory board or a compilation of scouts (avoid agents' opinions, as they are the devil) would tell him, his decision should come down to two things:
1) does he have things he needs on film to mitigate the risk an NFL team has to take by drafting him
2) can he actually work on those things, and get better, while in college
3) can he reduce his own risk of staying (through sufficient insurance or the like)
4) if he improves those things, does he stand to significantly increase his chances of guaranteed money and potential longevity in the NFL?
If he goes through that flow, alone or with a group he trusts, and it comes out to 4 yes answers, you automatically stay.
If he goes through that flow, alone or with a group he trusts, and it stops with a NO before the #4 , you automatically stay.
If he goes through that flow, alone or with a group he trusts, and he's not sure about #4 , use the information shared with you by the advisory board and scouts.
As I've been saying, I think it's a bad decision for him to leave right now. I also think our football team is in better shape with him than without him. I know some disagree on that, but I believe we're setup for a multi-year run if he stays.
Lu,
That was 4 things
