Exactly how binding is the agreement between player and school once the aid papers are signed. I know there is out if the head coach leaves, but my understanding is that financial aid isnt binding and nothing is set in stone until the kid enrolls. You know where this is going, kids are already signing as late in the day as possible to keep the bidding going, but what about the schools that lose kids at the last minute and now have leftover funds? What keeps them from trying to steal a kid that has already signed?
