After being poached almost into oblivion, the Pac-12 is fighting off extinction by plucking schools from the Mountain West.

The Pac-12 announced Thursday that it in 2026 it will add Boise State, Colorado State, Fresno State and San Diego State alongside Oregon State and Washington State in a rebuilt Conference of Champions.

The additions rob the Mountain West of four of its more prominent schools and successful football programs, most notably Boise State. It still leaves the Pac-12 two schools short of the eight it needs to have in place in two years to be recognized as a conference by the NCAA, so more moves are expected.

The Pac-12 and the departing schools will likely be on the hook for about $110 million in exit fees and penalties to the Mountain West.

It is a remarkable bounce-back move by a conference left for dead a year ago when 10 members scattered to competitors across the country after being unable to secure a lucrative media rights deal that former Pac-12 schools such as Southern California, Oregon, Washington, Utah and Stanford believed would keep them competitive with other leagues.

“For over a century, the Pac-12 Conference has been recognized as a leading brand in intercollegiate athletics,” Commissioner Teresa Gould said in a statement. “We will continue to pursue bold cutting-edge opportunities for growth and progress.”

The Pac-12 said it evaluated potential new members using five criteria: academics and athletics performance; media and brand evaluation; commitment to athletics success; geography and logistics; culture and student-athlete welfare.

Two for a time

The Pac-12 is currently operating as a two-school conference, with Oregon State and Washington State the only remaining members, taking advantage of NCAA rules that allow for a two-year grace period. Oregon State President Jayathi Murthy and Washington State President Kirk Schulz welcomed their new conference mates in a joint statement.

“We eagerly anticipate their uniquely insightful contributions during this transformative era for the conference and collegiate athletics,” they said.

Oregon State and Washington State have a football scheduling agreement in place this season with the Mountain West, giving them six opponents each from the league. A Sept. 1 first deadline to renew the deal came and went.

Part of that deal included millions of dollars in additional fees for the Pac-12 if it poached Mountain West schools.

Oregon State and Washington State should be able to afford the fees that remain. While the schools have publicly downplayed having a war chest, they do have about $250 million at their disposal from the two remaining years of the current College Football Playoff agreement; a contract with the Rose Bowl that expires after 2025; revenue accrued by Pac-12 teams in recent years from NCAA men’s basketball tournament units; and Pac-12 Network assets.

Oregon State and Washington State also have an affiliate membership in place for this school year and next with the West Coast Conference for men’s and women’s basketball and other Olympic sports.

Best of the rest

Leaders at Oregon State and Washington State have insisted since the Pac-12 collapsed that unless an invitation came from a power conference their priority was to keep the Pac-12 alive.

Whether the Pac-12 will be considered a power conference again, on par with the Big Ten, SEC, ACC and Big 12, seems unlikely, but the league is trying to position itself as the best of the rest — especially in football.

Boise State is the most notable addition as the strongest and most consistent football program outside of the power conferences for more than two decades. The Broncos have 16 double-digit victory seasons since 2002, when they were members of the Western Athletic Conference.

“What a great day to be a Bronco!” Boise State athletic director Jeramiah Dickey said.

Left behind

The Mountain West will be left with Air Force, UNLV, Nevada, Utah State, New Mexico, Wyoming, San Jose State, Hawaii as a football-only member, and an uncertain future.

Commissioner Gloria Nevarez said late Wednesday that the MWC board of directors was meeting to discuss the next steps.
