I am bothered by the phrase renege on his commitment.
All of these commitments are contingent in both directions. He can lose his scholarship, he can be recruited over, the coach can leave or be fired, and probably more scenarios that I can not think of. There is a long history of schools and coaches doing what is best for them, but not best for the individual athlete. Why should the athlete not consider what is best for him? Hell, this board has a field day when PSU recruits over an athlete. We even coined "getting Nevilled".
It never ceases to amaze me that people are so bothered by symmetry. Or maybe it is change. I don't know.
