OK. So let me get this straight:
Texas saves the Big 12, and stops the expansion dominoes from tumbling, by opting to stay in the Big 12, thanks to a chunky new TV deal that rewards it handsomely, and some would say outrageously. But Nebraska flees to the Big Ten and Colorado bolts to the Pac-10 before Texas, the key player in all of this, spurns the Pac-10 and/or the Big Ten, thereby reducing the Big 12 to 10 schools.
Meanwhile ... now that Nebraska has joined the Big Ten, that conference has grown to 12 schools.
So the Big 12 is now, theoretically, the Big Ten. And the Big Ten is now, theoretically, the Big 12. But the Big 12 (Ten) will still call itself the Big 12, and the Big Ten (12) will still call itself the Big Ten.
