re: Butch Jones, this will bite you in the arse...

A commitment is non-binding, a scholarship offer should be conditionally binding.

Without a revelation concerning character, grades or legal issues a scholarship offer accepted in form of a commitment should be upheld, and in the event the school wants to pull the offer in favor of a more talented prospect then the NCAA should penciling them with a loss of a scholarship the following year.
A kid decommiting isn't going to be the difference between a school continuing to have a football program, but dropping a kid on his head this far into the process could be a reason he doesn't end up in a positive situation football wise. Not that going to a school that doesn't want you but is obligated would be a better situation would be much better.
All the guidelines concerning offers and commits should benefit the student athlete. Schools do not have to accept commits on the spot, and they would need to be more selective and cautious when it comes to recruiting. It's getting a little out of hand as is.

But Butch Jones is an a-hole! And to quote Tyler, "Get fricked!"
