5 conference champs plus highest ranked G5 conference champion.
Top two seeds get bye.
3 vs 6, 4 vs 5 on third Saturday of December.
Semi-finals New Years Day.
Championship Game one week later.
No more “gaming the system” since only one school per conference gets in. Being undefeated matters (because it will likely get you a bye in the first round of the playoffs). Regular season matters because you have to win your conference to get in. All Division 1 teams have a chance because Group of 5 is guaranteed a slot.
Based on the final Playoff Committee Rankings in 2017, here would have been the seedings and first round games:
1. Clemson (bye)
2. Oklahoma (bye)
3. Georgia vs 6. Central Florida
4. Ohio State vs. 5. USC
