The Big XII has agreed to a more equitable distribution system for its revenue. It's still not entirely equal, but whatever - Considering over 1.1B dollars just went on the table this isn't peanuts.

What does this mean?
A) Texas isn't leaving. I'd bet my next paltry government paycheck on that. With literally BILLIONS coming in now, they are in a postion to settle the others member down, and they are doing it - "Hey boys, sorry about any misunderstandings, were with you, lets work it out."
B) The Big XII isn't expanding, or at least, not for another 5 to 10 years. No need to. The loss of the Denver market has done nothing to keep the money from coming in.
C) The only question now is how the loss of the Championship game affects the conference. The B1G thought it was severely hurting their on-the-field performance, with the loss of both money and revenue, and that's why they brought in Nebraska. If the Big XII starts to fall behind on the football field, then in a few years they will start talking expansion again.
