I don't see that happening. IMO, the orphaned XII won't be able to draw as much money as PAC teams when the dust settles on this with any added teams, whether PAC or not.
If you're an Arizona school or the Yewts or CU, you would still rather be tethered to USC, UCLA, Oregon and the Rose Bowl than TCU, TTech and and Oklahoma State for cultural, geographical, and a myriad of other reasons.
I simply don't see the re-branded XII being able to bring in more money than the PAC for the long haul. It's not sexy enough anymore.
GO COUGS.
