Verbal commitments are easy to get out of. Even written contracts mean little any more. I sign to play four years for LSU. If things look real good, I turn pro. If I'm the coach but the money is right, "Bye." i.e. Saban.....If I am a pro player and have a really good year, I want to renegociate or I'll just sit out. But never do you hear of one saying that he doesn't feel like he earned his money this year due to a crappy season so I'm gonna refund part of the money.
