At least ESPN/Disney (and their gambling arm) as well as the advertisers need to figure out how to not make a mockery of this, or they are going to lose even more eyes. Which is something ESPN/Disney have been struggling with for years.
Well, with all NY6 bowls going to playoff games next year, that solves the issue for the biggest bowls. Though I feel like attendance will dip. I'm not sure the money is there for fanbases to go to a quarterfinal bowl and then a semifinal bowl. I also haven't heard if the Rose Bowl budged on their Jan 1st date or not. They might be permanently locked into a quarterfinal if that's the case.
The other bowls I'm not too sure if opt outs will really affect those. Will anyone care if the Fenway Bowl has a lot of opt outs? Are those teams even going to deal with a lot of opt outs?
During the Orange Bowl they had an interesting look at the bracket for next year. They used this year's results with next year's conferences. Obviously that would change the schedules and so a team like Washington or Michigan may not go undefeated if they are also playing Oregon, but it did highlight the discrepancy in having the top four be fixed to the conference champs, especially with no divisions and larger conferences meaning you could technically have two undefeated teams after the conference championships are played. It also assumed that they will move to the 5 champ + 7 at large format now with the Pac 12 collapsing versus the 6+6 currently set to take place.
First round would be: #ranking, (seed)
#23 Liberty, CUSA champ (12) at #2 Washington (5)
#10 Penn State (11) at #4 Alabama (6)
#9 Missouri (10) at #6 Georgia (7)
#8 Oregon (9) at #7 Ohio State (8)
Quarterfinals:
Rose Bowl: UO/OSU vs #1 Michigan, B1G champ (1)
Sugar Bowl: Mizzou/UGA vs #3 Texas, SEC champ (2)
Peach Bowl: PSU/Bama vs #5 Florida State, ACC champ (3)
Fiesta Bowl: LU/UW vs #14 Arizona, Big XII champ (4)
I would guess the committee would fiddle around with the rankings to avoid two intra-conference matchups in the first round as well as a guaranteed intra-conference matchup in the Quarters. Though a possible OSU-Michigan match-up in the Rose Bowl is probably a network and advertiser's greatest dream.
