I wonder if we could realistically get Louisville and Missouri into the Big 12. Does Missouri really like being in the SEC, other than so they can say "FUCK YOU HA HA WE DON'T WANT TO PLAY YOU" to Kansas? Pitt to me is too far East, and I really think they identify with the East Coast too much to want to be in a conference with a bunch of schools in the geographic middle of the country.
What makes the most sense for us is middle-of-the-country expansion. If we could get Nebraska, I'd be in favor of that but I don't see that happening. I don't think we could get anyone out of the Big Ten. There aren't a lot of attractive candidates in the state of Texas now that we have TCU-- I just don't see Houston as a value add, SMU and North Texas are total G5 programs. There also aren't any FCS programs ready to move up where they'd make sense.
Boise is intriguing. Utah would have been good. I'd take BYU.
All of the above is strictly me wrestling with realistic scenarios-- what I would prefer is a Big 12 without Colorado, but with A&M and Nebraska. That was this conference at its best. Or, moreover, I'd like to see a massive realignment that took the conferences down to no more than ten teams playing an internal round-robin with no CCG and the champions receiving one of eight available post-season bids. Texas' best conference would be playing OU and Arkansas and A&M every year, plus other Texas schools, and a couple of marquee games out of conference that no longer determined if we got into the playoff or not (e.g., you could play and lose to Alabama and Ohio State, but win the conference and get into the playoff).
But that's not realistic.
