Hindsight is 20/20. I thought they made the right decision at the time once it was clear Texas had destroyed the conference thru its own greed.
I thought they did too, and it's hard to argue that leaving the Big 12 was a bad idea. It just happened to be at a bad time for them, and while it was the only logical move for them, it would appear that in the long term it will most likely be a bad place for them.
