Montana talked to WAC sometime in 2009, and decided not to join.
"Following 2009, the Western Athletic Conference (WAC) experienced a severe and continuous loss of members, which ultimately led to the suspension of its top-tier Football Bowl Subdivision (FBS) football competition and a major realignment.
- Massive departures: Between 2011 and 2013, the WAC lost nearly all of its members, many of whom joined the Mountain West Conference or Conference USA.
- Loss of key football members: High-profile defections included Boise State, Fresno State, and Nevada in 2011–2012, followed by Hawaii, San Jose State, and Utah State.
- Elimination of football: After the 2012 season, with just two football-playing members left, the WAC announced it would cease sponsoring FBS football. It transitioned into a non-football conference, focusing on basketball and other sports."
- "Boise State announced it was leaving the WAC on June 11, 2010, to join the Mountain West Conference, effective July 1, 2011.
- Announcement Date: June 11, 2010.
- New Conference: Mountain West Conference.
- Effective Date: July 1, 2011."
"During the week of June 7, 2010, amid rumors surrounding Boise State's future in the WAC, the conference held a meeting of its athletic directors and university presidents in
Las Vegas to discuss contingency options. The conference fully expected to lose Boise State, and according to WAC commissioner
Karl Benson, there was no bitterness toward BSU by the rest of the current membership. Benson also added that the WAC was considering expanding itself, with the conference eyeing up to six current members of the second-tier
Football Championship Subdivision.
Boise State left the WAC for the Mountain West at the end of the 2010–2011 season. On August 18, 2010, Nevada (Reno) and Fresno State were both extended invitations to join the Mountain West Conference, and subsequently accepted."
