I suppose you blame battered spouses, too.
Seriously, that's nonsense. You expect TTU, Baylor, and TAMU to stick around in a conference that DOESN'T include UT? We can debate who's to blame for conference until the cows (longhorns?) come home. The fact is EVERY school is to blame, because the administrators failed to make the necessary agreements early on to take advantage of all the natural benefits the Big 12 could have provided. UT should have been more collaborative. The old Big 8 should have been more unified during the merger. We've never had strong conference leadership.
At the time, the Big 8 needed Texas, and the TX 4 needed the Big 8. That's no longer true. As more and more power shifted to the south, only single schools (NU, MU, etc.) stood up to protest, and only when it threatened their own narrow interests. That's everybody's fault.
As somebody said earlier, Missouri only has leverage right now because it has another option. Last year it didn't, and it was forced to agree to the UT/OU conditions. If ISU had the option, the fan base would be LIVID if they refused to pursue it in the name of "conference unity."
It would depend on the option. I want no part of ISU in the SEC. Ever. I love the idea of ISU in the B1G. If Mizzou was entertaining an option to that league, I would completely understand why they would want to move there.
The SEC on the other hand seems foolish. All I see the SEC providing Mizzou is stability, and stability is something they could have in the Big 12 if they stay. Mizzou will NEVER get left out in the cold as long as Kansas City and St. Louis are part of the state of Missouri.
I hope that Mizzou just uses this as leverage against Texas because, I think the more geographically centered the Big 12 stays, the better. The Big 12 is going to add schools with or without Mizzou, but I'd rather have that old rival be part of the league.
