Well the Texas AD has the support of the Texas president and the Texas Board of Regents, so everyone there is on the same page except faculty. The Texas governor is a Texas ex with 50 yard line seats for years, so he won't let the legislature screw with Texas.Sounds like your athletic department is trying to pull a Bobby Lowder type move.
How is OU getting unhinged from OSU?
I don't know how OU will pull this off. The Oklahoma Governor is an Oklahoma State grad and the Lt Governor is Chairman of the Oklahoma State board. In the past it was made clear to OU they couldn't leave Oklahoma State in the lurch. However, OU is making the case that with Texas definitely leaving, with or without OU, the Big 12 is effectively dead and you can't blame OU for grabbing the SEC life preserver. They have no way to maintain the status quo, the Big 12 is a sinking ship without Texas (to maintain the life preserver metphor).
