The College Football Playoff is considering an expansion from four to 12 teams. Six spots would be reserved for the highest-ranked conference champions plus six at-large selections. Such a plan would triple the number of teams with a shot at winning the national championship. The four-team playoff was implemented in 2014. Its popularity seems to have waned since only a few teams have grabbed the majority of the spots, led by Alabama and Clemson. The soonest such a plan might be in place would be for the 2023 season. It is more likely to be after the 2026 season.
