I’ve never been a fan of the XII. I liked the Big 8, and maybe they should have merged with the Big Ten instead. But that ship has obviously sailed, so the proverbial “what if’s” have no merit. As for the old SWC, meh. You had UT, A & M, and TCU produce good seasons every now and then, but no long-term stability. Hopefully the new additions coupled with UT and Oklahoma bolting will result in a better league.
