10 stay together, is being significantly overestimated on CB today.
I could see scenarios where the remaining ten PAC schools convince Texas Tech, Kansas, Oklahoma State, and Iowa State to move over.
In that scenario, the Big 12 would look a lot like the Big East (AAC precursor) that TCU was originally going to join before it punched its ticket to the 2012 version of the Big 12.
Of course, if the Big Ten adds Oregon, Washington, and Stanford, the Big 12 is clearly in the power position...but I see a lot of comments on CB today that could blow up in our faces if things don't break the way we hope.
