You're insane.
First off, for SU, the kid is committing to a program, not a coach. The transition is being developed to be seamless. The kid knows what the change will be, just not when it will happen. The kid knows 10 years from now, when he comes back to visit he will go into the locker room and be greeted by Hop. Don't be trying to spread that UConn stink over here just because the coaches have the same first name.
Secondly, yes the kid could change his mind. But SU has a good track record of keeping kids who make the early commitment. There have been no regrets with Dion or MCW. Much easier to keep a kid than it is to win out in those shady late Spring recruitments.
Third, it would look great in the eyes of a 5 star big. Looking down the road they would see Ennis, and then Briscoe at the guard spots, and want to join that combo. To get that honor they should realize they should sign on early and be prepared for a year of back up duty, because that is the way we like to break them in here.
So please, keep your delusional rationalizations on some other board. Getting an early commitment from Briscoe to SU would be fantastic.
