The question is do any of those other schools in the Big 12 really amount to anything, as far as earning the AAC more tv revenue? Let's say hypothetically Kansas and ISU go to the B1G. You're left with Oklahoma State, Kansas State, TCU, Texas Tech, Baylor and then WVU. Take WVU out of the equation. If 3 of them join the AAC, are combined they worth an additional 20+ Million per year for the AAC? My guess is probably not. Maybe some combination of two Texas schools and Oklahoma State. But it's questionable.
I guess it comes down to if you'd rather make the money, the best bet is probably independence. But if you want better access to the CFP, it probably means you gotta go G5.
