because a lot of the rest of the schools don't want to play in the UT-Austin 12.
If Alabama and Florida were allowed to dictate everything in the SEC including how much money they got, how long do you think it would be before Auburn, Tennessee, Georgia, and LSU were looking to bolt to another league where they got an even split?
It wouldn't take them long, and of course we'd be left out on the cold.
The Big 10 and Pac 10 tried to make it happen this past year. Colorado and Nebraska were smart to get out while they had the chance. The rest will follow suit eventually.
I expect Texas will likely one day be an independent, and the rest of the strong Big 12 schools will bolt for other leagues, with some of the lesser programs left out in the cold to join the MWC, namely K-State, Baylor, Texas Tech, Iowa State, possibly Missouri.
