I am curious, in the past, the draw was tv sets. Bring them in a geography that you want and don't have, and you are desirable. What now? Some of the AAC school have good to very good academics, others not so much. Some large enrollment, others are small.
I guess the primary driver is money. How can expansion be spun to re negotiate the TV deals. The ACC needs a much better deal but with 2 AAC teams in Fl, the Florida teams are unlikely to be joining, maybe Cinci?
I do think the Big 12 will move quickly, so the wait to see the first moves will not be a long one IMO.
