I'll be honest, it sort of looks like UGA and everyone else right now.
Ohio St looked dreadful (it was is not nice weather) yesterday and looked mediocre against Penn ST.
Mich was losing at halftime to Rutgers before turning off the jets.
Oregon looks great right now. Probably #2 behind UGA.
TCU keeps playing with fire but winning.
I think TN gets in if they win out (and they will be heavily favored in their last 3) and UGA beats whoever comes out of the SEC West (likely either Ole Miss or LSU). TN would be the top ranked 1-loss team in that scenario.
If the team that wins the PAC CG has 1 loss I think they are likely to get in (Note that USC and UCLA play each other yet so one of them has to take a second loss).
We are down to just 4 unbeaten teams - UGA, OSU, MI, and TCU and one of OSU/MI has to take a loss.
FWIW, Notre Dame has won its last 27 regular season games against ACC opponents - it's last regular season loss to an ACC team was to Miami at Miami on Nov 11, 2017.
It did lose to Clemson in the ACC Championship game in 2020 (Covid year) and also lost to Clemson in the 2018 Cotton Bowl.
Given all they have left this year is BC, it seems likely they will have won their last 28 regular season games against ACC opponents going into the 2023 season.
