the Big 12 situation turns out for the remaining schools, no matter what BYU decides to do (go to the new and improved AAC, go to the corpse of the Big 12, stay Indy), it will almost certainly be the wrong decision and work out in a less than ideal way.
So just get ready to be disappointed. We'll agree to join the Big 12 the week they break up, or we'll go to the AAC and everyone will stay put and try to make the Big 12 work, or we'll stay Indy when we could succeed and in a new and improved AAC.
It will work out poorly for us and we'll be on the outside looking in. Why do I think this? Because NONE of these schools are incentivized in any way to split their pie more ways. In short: it's every man for himself right now and no one is going to bring us along for the ride.
