If you have looked at the Clemson Football schedule and thought it looks a bit odd, don’t worry. You’re not wrong.
The Atlantic Coast Conference decided to do away with the divisional alignment that the league had used since 2005. Clemson had been a part of the Atlantic Division since that time and played all division members every season. They also played their crossover rival, Georgia Tech, every season.
When the divisions started in 2005, each had six teams. With six fixed annual opponents, Clemson rotated among the other teams in the Coastal Division. This meant the Tigers would face all their conference opponents at least once every third season, and would visit each opponent’s stadium every six seasons.
