Like will said below, Texas makes the rules in the Big 12, I'm surprised they'd ever want to leave - but if they did, wouldn't they rather form the money team with Michigan-Ohio State-Nebraska-Oklahoma-Texas and just rule the central tract of the country? And Oklahoma, regionally makes sense obviously, but wouldn't they rather maintain Texas and revive Nebraska rivalries full-time rather than enter the gauntlet?
Competitively and (kind of) financially it seems a little misguided
