Playoffs would be 1 Alabama vs 4 Ohio St in the Sugar and 2 Notre Dame vs 3 Clemson in the Rose.
Orange Bowl wins get highest remaining ACC team in Miami against highest remaining SEC or Big Ten team which would be Texas A&M.
Big 12 champ Oklahoma and Pac 12 champ Oregon would both need spots along with G5 champ Cincinnati. That would leave 3 remaining at-large spots going to highest ranked remaining teams in Florida, Northwestern, and Georgia.
