They are inevitably going to have to expand this thing to at least 16 teams because their decision to include auto-bids, regardless of ranking or any other metrics attached to it, is going to really bite them in the ass this year. There are at-larges like ND, Texas, and Bama that are way more deserving than the joke of an ACCCG. Part of me hopes Duke wins the ACCCG just to make the Committee and these conferences look like fools.
Make it 16, but you can't have X number of teams from each conference guaranteed a spot. I don't know the optics of how removing the auto bids would affect the G5 participation, but I have way less issue with that large of a field (66 teams) getting ONE auto-bid vs. a potential 7-5 ACC champion. I highly doubt that the P4 teams would agree to keeping a G5 auto-bid with any strings attached to their own, though.
I'm not sure what the best solutions are but this is a complete joke of a system.
