Well done, exactly right. The only reason Oklahoma and Texas want this now is because they no longer have options.
Oklahoma can't go to the Pac 10 with Oklahoma State dragging it down. Door slammed shut, otherwise Oklahoma was GONE.
Texas can't go anywhere with Longhorn Network and Texas Tech dragging it down. Doors slammed shut, otherwise Texas was GONE.
They now know they can't go anywhere else, so they want to remove that option for all other schools, too. The message to Iowa State and others is: we have to stay, so you do, too. And Missouri, said, uh no, we have options, so F you.
And you know all this because??
I think it's pretty clear that in 2010 the six teams were strongly considering leaving for the PAC. It was all lined up to go, but they took a moment to think about it and realized that the Big 12 was a better conference for them.
The Aggies did not want to go to the PAC and preferred the SEC. There were rumblings even then that they did not want to stay in the conference and where there was smoke there was fire. As we've seen, statements came out that even while they said they were committed to the Big 12 they had already planned to leave for the SEC.
Look at the teams who left in 2010: Colorado who had already tried to go to the PAC in the 90s' and Nebraska who left due to the (at the time) vastly greater money available in the Big 10. Both moves made geographic sense.
Fast forward to 2011. The Aggies come up with a poor excuse to claim they were wronged and decide to bolt for the SEC. As we know, they had a chance to be in on the Longhorn Network as a joint UT-ATM network and declined it. Texas even relented on all the controversial parts of the Longhorn Network which A&M had objected to. This causes instability in the league again. I don't know if rebeccacy is right or wrong, or if he has any inside information at all. I'm inclined to believe he does have at least some information, but probably not at the highest levels. Either way, I believe that UT & OU remained committed to the Big 12 for the same reasons they stayed the last time: it's a great league where all their traditional rivals are, they don't want to be in a league with 4-5 national championship contenders who would beat each other up, and the money is good enough here.
As far as Missouri goes, I honestly don't know. I'd prefer they stayed, but I believe the Big 12 is on the right track again. We are now in a position where BCS conference quality teams want to come in to our conference. I don't think that can be understated.
