Head coach Mike MacIntyre returned for his third season with San Jose State. Under MacIntyre, San Jose State went 1-12 in its 2010 season and improved to 5-7 in 2011. On December 10, the University of Colorado at Boulder hired MacIntyre to be the new head coach of the Colorado Buffaloes football team. With a five-year, $10 million contract, MacIntyre would annually earn nearly quadruple his annual salary at San Jose State. The following day, San Jose State named defensive coordinator Kent Baer to be interim coach for the 2012 Military Bowl on December 27, in which they defeated Bowling Green 29-20. The previous week, MacIntyre stated that although other schools had contacted him about potential job openings, MacIntyre was not actively seeking another job. During San Jose State's late-season win streak, speculation occurred that MacIntyre might become head coach at Cal or Kentucky in 2013.
The 2012 schedule was officially released on March 5, 2012. The schedule had six home games and six road games. Because the WAC had only seven football member schools by 2012 due to conference realignment, San Jose State played six conference games and six non-conference games for the season. San Jose State played against all six other WAC member schools: Idaho, Louisiana Tech, New Mexico State, Texas State, UTSA, and Utah State. The non-conference games were against: Colorado State and San Diego State of the Mountain West Conference, Stanford of the Pac-12 Conference, UC Davis of the Big Sky Conference, and FBS independent schoolsBYU and Navy. On November 3, San Jose State became bowl eligiblefor the first time since 2008 after beating Idaho and attaining six wins against FBS schools. However, the win over UTSA did not count, because UTSA was not yet a full FBS member school. Six games were nationally televised this season. ESPN showed the Military Bowl on December 27, ESPN2 showed the games against BYU and Louisiana Tech, CBS Sports Network showed the game against Navy, and Pac-12 Network showed the game against Stanford. WatchESPN also streamed the games shown on ESPN and ESPN2 as well as two games—the ones against Colorado State and UTSA—broadcast by ESPN3, the game against New Mexico State via New Mexico State's AggieVision network, and the game against Utah State via ESPN Regional Television. KLIV in San Jose served as the flagship station for the San Jose State Spartans Football Radio Network, along with fellow affiliates KION in Salinas and newcomer KFIV in Modesto. Michael Spero returned for his second season as play-by-play announcer, with Kevin Richardson at color commentary.
