Granted, we probably won't ever get to hear both sides, but I cannot imagine a scenario where the college prohibits the kid from doing what he wants to do. You suck it up, no matter what, and move on. Anything else results in exactly this kind of PR headache.
If I were running the world, I would save this kind of spitefulness, if that's what it is, or persistence, if that's what it is, for the college coaches who bail out of contracts because the grass is greener elsewhere. Out here where I live, ASU just hired a football coach who bailed from his previous job after only one year, having bailed out of his previous job after only a couple. Why universities allow this kind of thing is absolutely beyond me. In this case, I figure ASU (an alleged educational institution for which I have absolutely no use) got exactly what it deserves, a journeyman coach who will turn on them in a heartbeat as soon as a better offer comes along. But I digress.
