re: How Would TCU Finish This Year If They Were In The SEC?

The PAC is still an option because UT wants to control their media rights still and the PAC 12 gives UT the best chance at this.
The PAC 12 network is controlled by the conference so if the conference would add UT and OU it would jump by at least 15-20 million in revenue per school.

Like you said the best option will be to stay in the Big XII and possibly add Tulane and Memphis.
