Air Force occupies a familiar place amid today’s college sports realignment news – sitting in a fixed position, watching the changes rotate around it like new constellations. On Wednesday a new Pac-12 will be born. Air Force’s longtime Mountain West foes Boise State, Colorado State, Fresno State, San Diego State and Utah State will join it. Those five will join Oregon State and Washington State, the last remnants of the old Pac-12, as well as Texas State.
