Boise State was originally set to join the Big East Conference , along with fellow Mountain West member San Diego State , for football in 2013 ; however , after the Big East announced a split between its FBS members ( which eventually became the American Athletic Conference ) and its non-FBS schools ( which kept the Big East name ) , Boise State announced on December 31 , 2012 that it would stay in the Mountain West Conference . San Diego State would later announce they would stay in the Mountain West as well , making the Mountain West a 12 team conference . The Mountain West formed divisions for the first time , with Boise State as part of the Mountain Division , and will conduct a conference championship game for the first time
