In the eight-year history of the College Football Playoff, only one conference has ever gotten two member schools into the four-team field — the SEC.
In 2017, Alabama joined conference champion Georgia in the bracket. In 2021, Georgia followed SEC champ Alabama. In each of those years, the two teams met in the title game, each winning once. Previously, after the 2011 season, SEC teams Alabama and LSU met in the then-BCS title game (the Tide won).
This was in part because of the undeniable strength of the SEC and part because of the circumstances of how the season played out.
