I agree, the NFL teams know that if he will quit on his team for his own interest in college because he doesn't "owe" them anything he will quit on his team when he is making millions, does he "owe" that NFL team anything? Carolina paid up front for his scolly for services to be given at a later date per that contract, just like the NFL teams are paying him with cash for a contract for services to be redeemed later.
I don't have any issue with him baling on his team and not honoring his end of the deal, but those players show have to pay the school back for his breach of contract. He should also have his name removed for every thing that ties him to the school. Records stats everything!
