I like expanding to 16, but I don’t love this system. For one, why the play-in games? That’s effectively just saying it’s a 20 team playoff with those bottom seeds pre-defined by conference.
Second, I think the system either needs to be fully prescriptive like the NFL where there’s no subjectivity (but at the risk of more deserving teams being left out) or mostly non-prescriptive where maybe 4 P4 and 2 G6 champions are in but the other 10 spots are simply by merit to get the best teams regardless of conference (which is subjective). So naturally, they’ve gone in between, which I think is the worst choice.
Personally, I think we’ve already devalued the regular season enough that we should fully lean into the playoff system. I would expand to 32 teams (eliminate conference championship games and these dumb play-in games) and keep it fully prescriptive so that a team knows exactly what they have to do to get in, like the NFL, and there’s no subjectivity. The NFL has proven that to be a good model, and the more teams you add to the playoff, the less people care if someone misses on a tiebreaker or something because they probably weren’t winning the thing anyways.
I would set a base number of teams (similar to NFL division winners), probably top 4 in each P4 and all G6 champions, and then let the remaining at large teams be applied to conferences before the season based on past performance in the playoff. So if the SEC wins a lot and the ACC doesn’t, then the SEC gets the extra teams. And if that changes over time, then it swings back towards the ACC, but everyone knows going in that you have to finish 7th in the SEC or 5th in the ACC to get in.
As a bonus, since the bids are pre-allocated to conferences, you have to be in a conference to get a bid. So screw you ND, get off your high horse and go fully join the ACC.
