top-12 (B12 and PAC) plus two ACC teams in the CFP and ACC #3 outside the top-12 (Miami or North Carolina).
Here's the NY6 using the current AP rankings:
Sugar(CFP): (1)Alabama v. (4)Clemson
Rose(CFP): (2)Notre Dame v. (3)Ohio State
Orange: (5)Texas A&M v. (10)Miami
Peach: (6)Florida v. (7)Cincinnati
Cotton: (11)Northwestern v. (14)Oklahoma
Fiesta: (8)BYU v. (9)Oregon
At large Bubble:
IN: (6)Florida, (8)BYU, (11)Northwestern
OUT: (12)Indiana, (13)Georgia, (15)Iowa State, (16)Coastal Carolina
There's a decent chance that the Selection Committee will rank Miami, Northwestern, Indiana and Georgia higher than the AP Poll and Cincinnati and BYU lower than the AP Poll. In that case, BYU will be competing with Northwestern, Indiana and Georgia for the last remaining at large spot and could easily be the first one OUT.
