Washington State and Oregon State, left behind in the realignment game, are charging forward with their plan to rebuild their 109-year-old conference. The Pac-12 made the first step official on Thursday, announcing the additions of Boise State, Colorado State, Fresno State and San Diego State for the 2026-27 competition year. But that only brings the Pac-12 to six schools. The conference must have at least eight by the summer of 2026 to comply with NCAA rules. It could expand beyond eight, of course.
