I voted for the Big East, because... it's not where I think we'll go, but where I want us to be. I want the Big East to stay alive. That seems unlikely, but it's better than anything else. I think we'll be in the ACC, but I don't want that.
Also, I don't think it would take many teams for it to stay together. If we added 1 good Big 12 football team with TCU joining, that would be 16 basketball and the same number of football as before with roughly the same level of quality. Probably better quality.
If more teams leave the Big East, then yeah, staying doesn't seem appealing. But my dream situation is one where no more teams leave.
