The realignment era
Conference realignment has fundamentally altered college football's competitive structure. What began with Texas and Oklahoma's move to the SEC accelerated into a cascade of departures, mergers, and rebuilds that left no conference untouched. By 2026, the sport has settled into a new equilibrium — though further movement remains possible as media rights cycles approach renewal windows.
SEC (16 teams)
The Southeastern Conference expanded to 16 members with the additions of Texas and Oklahoma, who officially joined for the 2024 season. The conference now stretches from Oklahoma to Florida, creating scheduling challenges but also the deepest talent pool in the sport. The SEC adopted a nine-game conference schedule format to accommodate the larger membership while preserving key rivalry protections.
Current members: Alabama, Arkansas, Auburn, Florida, Georgia, Kentucky, LSU, Mississippi State, Missouri, Oklahoma, Ole Miss, South Carolina, Tennessee, Texas, Texas A&M, Vanderbilt.
Big Ten Conference (18 teams)
The Big Ten's expansion to 18 members — adding Oregon, Washington, USC, and UCLA — transformed it from a Midwest-centric league into a coast-to-coast conference. The additions brought premier West Coast brands and created new scheduling dynamics, including significant travel distances that have altered the traditional Big Ten Saturday experience.
Current members: Illinois, Indiana, Iowa, Maryland, Michigan, Michigan State, Minnesota, Nebraska, Northwestern, Ohio State, Oregon, Penn State, Purdue, Rutgers, UCLA, USC, Washington, Wisconsin.
Big 12 Conference (16 teams)
After losing Texas and Oklahoma to the SEC, the Big 12 rebuilt aggressively by adding Arizona, Arizona State, Colorado, and Utah from the Pac-12, along with BYU, Cincinnati, Houston, and UCF. The result is a 16-team conference with a geographic footprint spanning from West Virginia to Arizona. The Big 12 has positioned itself as a competitive Power Four conference with strong football programs and growing media value.
Current members: Arizona, Arizona State, Baylor, BYU, Cincinnati, Colorado, Houston, Iowa State, Kansas, Kansas State, Oklahoma State, TCU, Texas Tech, UCF, Utah, West Virginia.
Atlantic Coast Conference (17 teams)
The ACC added SMU, Stanford, and Cal to offset departures and maintain its footprint. The conference's grant-of-rights agreement has kept its core membership intact despite speculation about further departures. With Clemson, Florida State, and Miami as flagship programs, the ACC remains competitive at the top while navigating questions about long-term media value relative to the SEC and Big Ten.
Current members: Boston College, Cal, Clemson, Duke, Florida State, Georgia Tech, Louisville, Miami, NC State, North Carolina, Pitt, SMU, Stanford, Syracuse, Virginia, Virginia Tech, Wake Forest.
Group of Five conferences
The American Athletic Conference, Mountain West, Conference USA, MAC, and Sun Belt continue to provide FBS football opportunities for programs outside the Power Four structure. The Pac-12's rebuild — centered around Oregon State and Washington State as holdover members — has added programs from the Mountain West and other conferences to reconstitute as a viable league. These conferences serve as development pipelines and provide competitive football that occasionally produces playoff-caliber teams.
What realignment means for schedules
For fans tracking schedules on CFBCountdown, realignment affects which opponents appear on a team's conference slate, when rivalry games are scheduled, and how non-conference scheduling works. Teams in larger conferences have fewer open dates for non-conference games, which can reduce traditional intersectional matchups. CFBCountdown's conference pages reflect the current alignment and are updated when official membership changes take effect.
