"The Big 12’s best chance at survival is sticking together — at least for now. Unless the college football oligarchs decide otherwise, the league can backfill from the AAC and the Mountain West while maintaining Power 5 status. College football is largely a consumer product, but the Sun Belt has shown playing the sport at a high level still matters.
While Big 12 schools each received $37.7 million in television revenue during the 2019-20 school year, that number will undoubtedly plummet without Oklahoma and Texas. Even with the drop off, those payouts may still be more lucrative than the $5.3 million each AAC member received this year.
On the field, a reconstituted Big 12 with Boise State, Central Florida, Houston and possibly an independent like BYU would expand the footprint and preserve a conference identity centered on high-powered offenses. Not to mention create compelling TV, which is ESPN’s endgame to begin with."
