Ignoring Oklahoma (and others) needs is going to send the BIG 12 down the path of the now defunct Big East.
Burying heads in the sand isn't going to make the Pac 12, SEC or especially Big Ten not covet schools like Oklahoma. You may not like expansion, but they do.
I know we disagree in a few areas on this but if you study the options for Oklahoma, there really aren't any. Neither the SEC nor the Pac-12 is going to add a single school even if it is Oklahoma. If they are going to jump into the court room over the GOR they are going to grab more than one school. That takes time and a lot of obvious effort to put together. It also means at least 2 schools headed to the SEC, but who would go with Oklahoma. It wont be Texas, it has everything it wants right now and can replace any school in the Big-12 even with bottom feeders and keep on going. If it is the Pac-12 they would need to add 4 schools. Which 3 go with Oklahoma? I just don't see either conference taking Oklahoma. Both have had the chance and passed when there was no GOR, I seriously doubt they try it now that there is one. The Big Ten is not going to look at a non-AAU school when UVA, UNC and Pitt are sitting out there.
