As long as Texas keeps their revenue stream at a high level they are not
moving. They clearly like being the big fish and having a good bit of control. OU is the key to this, no one else in that conference is that desirable on their own.
I can’t imagine that either UT or OU think that their football program would be helped by going to the B10 so unless the money tree dries up they probably hold tight for a while. It’s clear that there is a path to the CFB playoff from where they are.
