It's not really that crazy. If they really want in the valley for all other sports that bad then all they have to do is promise road games to all MVC voting members in the MVFC (plus Drake). They would get a majority of the votes needed to be added to the MVC. Crazier things have happened.
For example, didn't BYU promise football games when they moved their non-football sports?
I'm not saying it will happen, but my point is that they need to offer something of value to the valley as they currently do not. Unless current valley members see Air Force as a good investment I would say no unless they bring something to the table.
