I dunno, being a good player doesn't necessarily equate to being a good coach. I think the most important thing he can do is just BE THERE, be visible on the sidelines, and be visible to recruits. Big schools like Alabama and LSU do that all the time, and I think it would be a huge boon to us as well.
I also think a really good thing he could be doing, both for us and for the game, would be to mentor guys who have suffered serious injuries, especially knee injuries, while they're in recovery. I think a nationwide network of guys who have been there and could commit to this could do a lot of good.
