1. This would require the B1G, SEC, and other conferences to agree that the ACC gets 2 spots in the playoff every year. Considering how much the SEC ****ed and moaned with SMU getting the 2nd spot in this year's playoff, I don't see them signing off on it. When it goes to 14? Maybe.
2. Does the ACC hamstring themselves in some years? What if there are 3 ACC teams that are in the mix? Admittedly, this would be rare, but they would be locking themselves in.
