The latest round of major realignment over the past couple of years was as crazy as it was unexpected.
But as the history of conference realignment shows, it wasn’t the first time schools in the West played a wild game of musical chairs.
Since 2000, at least 30 schools have changed conferences, become independents, or reclassified their divisional status at least once. Some have done so on several occasions.
However, the shuffling goes back much further than that.
Here’s a year-by-year breakdown of the most significant conference changes and reclassifications since 1902.
2024
In a turnaround that surprised many, the two-member Pac-12 announced plans to add five Mountain West schools—Boise State, San Diego State, Colorado State, Fresno State, and Utah State—beginning on July 1, 2026.
Gonzaga was also added as a non-football member.
The Mountain West, meanwhile, added UTEP as a full member and Northern Illinois as a football-only member. UC Davis and Grand Canyon were added as non-football members.
Hawai’i, which previously competed only in MW football, became a full member, adding basketball.
