Who is this "Big 12" that you speak of??
Personally, I believe that the Big 12 will fragment, now that it has been made public knowledge that it is all about Texas, and everyone else can be damned. Frankly I was surprised that OU and OSU hung around when Nebraska and Colorado announced they were leaving. I am sure that there are other conferences that would love to have a OU, OSU, or even a Missouri to add to their conference. If Missouri had not been so arrogant and try to put a gun to the Big 12's head in such a public way, they may have come to the Big 10 with us, but after the Big 10 seen that display, they wanted no part of it, and didn't even seriously consider taking Missouri, which would have been a pretty good fit when it came to sports - though I am not convinced it would have been a good fit academically. I am also sure that Texas will always be looking for a better home, where they can make more money...and wouldn't be surprised if they up and decided one day that they were leaving, and the other Texas schools were forced by politicians to go along for the ride.
Texas is what Notre Dame was when they made a deal for their own TV contract a few years back. They are showing their arrogance, and it will come back to bite them in the end. Notre Dame is not viewed in the same perspective as it once was, and if it wasn't for the loyalty of the Catholics, I would even venture to say that it would be viewed a 2nd tier opponent even more than they are now. Eventually Texas' greed will catch up to them.
