I can definitely see how the North schools felt slighted, but how does that move translate into the beginning of the Big 12's front office running the conference into the ground? Are you suggesting that the Big 12 wouldn't have been so inept had they not relocated their offices and remained intact in KC?
No, I am suggesting that Mizzou and Nebraska would not have such strong sentiments about ditching the B12. I think Wieberg and Bebee are inept, but not solely based on subpar television deals...and Bebee could certainly make the claim that of course the SEC got a better deal becuase theirs is newer. But with the climate created (in part) by ditching KC, those schools aren't wanting to listen.
This is pure speculation, but deep down UT wants to keep the B12 around AND have its own network. Deep down OU wants to keep its rivalry with UT and so that makes staying in the B12 the most viable option. aTm just wants to feel important, but their athletic department needs the money, Mizzou really wants to leave and is practically begging the B10 to give them an invitation and Nebraska is very similar to aTm, they just want respect wherever it is they go and probably see this as an opportunity to get some.
