Every school used to play 10 regular season games, then it increased to 11. Then, in the late 90s, when one of the BCS’s excuses for not having a playoff was the extra games for the student athletes, they increased to 12.
Add the conference playoffs, bowl games and the playoffs and it’s even more. For the 2017 season, Georgia played in the SEC championship and got to the national championship game ended up playing 15 games while Alabama played 14.
