I always kind of figured that Mizzou would be a good fit, since they have had a basketball program in the past, and there are plenty of TV's in Missouri, plus the location. And it would be a natural rivalry for Iowa and Illinois with them being on the border.
I don't really want Texas going, I am tired of their crap at this point. And with A&M being glued to them at the hip, I can't really say that it is all that desirable in my view.
Here is another thought, if it were Nebraska, Texas, and A&M from the Big 12, does the rest of the league putter on as a 2nd tier conference, or would they break up, and where would they go? Oklahoma and OSU would have no problem finding a home in the SEC (and there is no way they would hang around if Texas and Nebraska are gone), but what about the rest of the Texas teams? The Pac 10 will only take them if they can get Texas, I am sure.
