This was originally intended to be the last season for Boise State and San Diego State in the MW . After the 2012 – 13 school year , both schools ' football programs planned to join the Big East . Both schools also planned to join the Big West , a former conference home of both , for non-football sports . San Diego State , a charter member of the Big West , was set to return to that conference after a 35-year absence ; Boise State was set to return after a 12-year absence . However , due to major instability in the Big East , culminating in the mass exodus of the conference 's seven basketball-first schools in December 2012 , Boise State chose to remain in the MW for 2013 and beyond . San Diego State has since sought to remain in the MW , and as a part of Boise State 's agreement to remain in the MW , the conference must offer an invitation to San Diego State to remain in the MW before it can invite any other school
