Yep I see OU and perhaps even Texas jumping to the Pac 12. And that will be the end.
Historically, Texas hasn't wanted to go anywhere where they couldn't be top dog (You have a Big 10 Network. You have an SEC network. You have a University of Texas network.)
Texas calling the shots is what forced TAMU to jump to the SEC. And earlier, Arkansas saw the handwriting on the wall and jumped, leading to the death of the SW Conf.
OK State should look to the SEC (although they won't bring many TV sets) and TxTech should look to the PAC. Split up most of the Big '12' among the 4 superconferences, and leave UTex to play by itself. They could schedule SMU, Tulane, Vandy, North Texas, and enough other similar teams so that they could always brag about their record.
