An 8-team playoff based on the Committeems rankings this year...
1. Bama (SEC Champ
2. Clemson (ACC Champ)
3. Oh St
4. Washington (PAC-12 Champ)
5. Pedo St (B1G Champ)
6. Michigan
7. Oklahoma (Big XII Champ)
8. Wisconsin
The three at-large bids wouldn't necessarily always be Conference Champs from the American, MAC, or MW...
Most of the time, it would end up being P5 teams getting voted in over smaller conference champs.
This year, it would the B1G playoffs, in other years it would be the SEC playoffs or Pac & Big XII...
The most ACC would ever get is FSU & Clemson, an 8-team wouldn't help us in the future any more than a 4-team does now.
Only way we ever get there is winning the ACC, even if we made it to the ACC title game & lost, they would never vote us in.
While an 8-team playoff may work in theory, in reality I don't think it would actually work.
A 6-team playoff might work though... The P5 Champs & 1 at-large, the top two seeds gets a bye, just like the NFL.
