The whole Stoops story originated with two boosters, who, without any authority from AU or any trustees, tried to contact Stoops on on their own. He said no. The boosters, not happy, decided to leak the story to try and force Gus' hand. That's basically where we are now. As far as I know, there has been no renegotiation.
ADAG has vetoed Freeze for 2 reasons:
1. Gus lobbied HARD for Chip, and his contract. He has an over $1 million buyout, and AU isn't going to throw good money after bad
2. The SEC will veto Freeze even if AU doesn't. Saban tried to get Freeze as ANALYST last season, and was told no. Do you really think they're gonna let us have him as an ON THE FIELD COARCH next season? No way Jose.
Edit to add: this info came from a board member
