On December 6, it was announced that head coach Chris Petersen would resign to take the head coaching job at Washington. In eight seasons at Boise State, he posted a record of 92–12, won five conference titles and two BCS games. Associate head coach Bob Gregory served as Boise State's interim head coach in their bowl game. On December 11, The Broncos hired former offensive coordinator and Arkansas State head coach Bryan Harsin as their permanent head coach.
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.
As part of the conditions for Boise State to stay in the conference, the Mountain West lifted the ban on the Broncos wearing their all blue uniforms at home during conference games.
This was the second consecutive meeting between the Broncos and the Huskies as they met at the end of the 2012 season in the Maaco Bowl Las Vegas. The 32-point loss is the worst loss under Chris Petersen. The previous highest margin of defeat was 14, also coming against Washington in 2007, Petersen's second year as head coach. Prior to this game, the Broncos' previous five losses had been by a combined 11 points. It was the Broncos worst loss since a 35-point loss to Georgia to open the 2005 season. This was also the first time the Broncos failed to score a touchdown since a 58–0 loss to Washington State in 1997.
