How about one of these?
Tell the WAC and the MWC that if they merge, they get a championship game and an automatic BCS bid for the winner.
TCU, Texas Tech and Boise State need to find their ways into tougher conferences. The 2 Texas schools could go to the Big 12—their locations would keep their travel costs down. Unfortunately, it would be tougher for Boise State. The Pac-10 would be the obvious choice, but their travel costs would increase, and they would have trouble finding a “travel partner.” (Look at a map of Pac-10 teams to see what I mean—e.g., ASU and UofA basketball teams play at USC and UCLA on the same weekend, and granted, Oregon and Washington teams are further apart.)
Texas Tech is already in the Big 12.
WAC and MWC used to be one division. They all used to be WAC until they split. Remember BYU won the national champs when they were in the WAC.
