Since the College Football Playoff format debuted in the 2014-15 season, replacing the Bowl Championship Series, there have been eight national championship squads — five between two programs.
Under this four-team postseason format where the playoff committee selects the top teams to face off for the national championship, the Alabama Crimson Tide have won the most so far with three titles in the 2015-16, 2017-18 and 2020-21 seasons.
