The Nova Home Loans Arizona Bowl begins a three-year window in which it is locked into the Mountain West and Sun Belt conferences. The game’s founder, Ali Farhang, who recently completed a deal to broadcast this year’s game on the CBS Sports Network, has some difficult choices to make. It’s possible that Air Force would agree to be an anchor “home team” for Tucson’s bowl game the next three seasons. The Falcons and their military connection are virtually a can’t-pass-up option. One good thing Farhang did with CBS was to negotiate an option to avoid conflict with Arizona basketball. The third Arizona Bowl will be played early in the afternoon on a Friday or Saturday on either Dec. 29 or Dec. 30, whatever date doesn’t correspond to Arizona’s likely debut for the Pac-12 season.
