IF the ACC disbands, it will be FSU 1st. UNC and Virginia have been mentioned as a targets as well. GA Tech makes a lot of sense IMO - maybe Miami.
I think it's more viable to go to a 16 team playoff. Keep the ACC intact, build out each conference to 20ish teams. (PAC 2 is already expanding so might have to give some room for the new G5s) and leave ND as ND wants to be.
However, it will be the networks that decide how this plays out...
The expanded playoff has made conference championship games obsolete. We need to cancel all CCGs and expanded the playoff to 32 teams. A 32-team playoff more than triples the games for TV, gives every conference a seat at the table and reduces the season duration by three weeks. This 32-team format has no conflicts with the NFL playoffs and the season would end on New Year's Day. Most notably, the Big Ten and the SEC would probably each land 8-10 teams into the playoff every year and their playoff payouts would double or triple.
Start the season on Week 0, something that has been proposed many times.
Give autobids to all four P4 champs and all five G5 champs. No conference gets more than one autobid. The autobids go to the four P4 champs and the five G5 champs only.
Seed the teams in the playoff as is done in March Madness, e.g., four #1 seeds, four #2 seeds, etc. Place the seeds in brackets that avoid repeat games to the greatest extent possible. Also, spread out teams from the same conference to the greatest extent possible to minimize same-conference games in the playoff.
As I said before, cancel all conference championship games.
“Rivalry Weekend” (Bama vs Auburn, etc.) would then be the week before Thanksgiving. This is actually better for most colleges because the students are still on campus.
Round One of the playoff, a 16-game extravaganza, is then played over the 4-day Turkey Holiday.
Round Two of 8 games is the first weekend in December.
Round Three of 4 games is the second weekend in December.
Round Four of 2 games is the third weekend in December.
NC game is then Dec 31 or New Year’s Day.
