My Cal and Stanford prediction. They both want the Big 10, but won't get it. If they both think they are too good for the Big 12, they will think they are too good for the new Pac 12/MWC. I predict Stanford will go independent. They can afford it. I predict Cal will go FCS and join the Big Sky.
Cal Tech is a globally elite school with no sports. It's private but as highly regarded as Cal. That would probably be too sudden of a transition to ever try.
