Everyone awaits the PAC media deal/places so much attention on it, but I think even if the PAC's deal equals the Big12's the final analysis will show that the Big12 will make a significant amount more in ancillary revenue including tournament payouts, creative marketing streams, etc.
Through those ancillary revenues, let's say Big12 schools make an extra 10m more annually. That's 10m more you can put into fb coaching staffs and recruiting budgets. In turn you can communicate to donors to not put funds into the general athletic fund/earmarked to fb but rather to pour their donations into NIL collectives. That's a huge advantage in terms of attracting players. Seems like that alone would make it easy math for the Colorados of the PAC to split. But of course there are other aspects in the decision to stay or go. Should be interesting to watch what happens.
