Edit: As I've previously stated, I think it is best for all parties involved if the Big XII network came about and all schools had an equal stake. But Austin didn't want it.
This is key. When the Big XII was at the edge of falling off the cliff (already lost Colorado and Nebraska with more defections reported), UT snatched that opportunity to take advantage of its bretheren and held the Big XII hostage to its very existence (UT at the time was flirting with the Pac 10).
That is not doing well within the system, that is being a bully.
