Oregon - Is 50/50, I'm not sold that they have a great defense, not sure how great their offense would look against ND's defense. Good size at DT for them would be an issue, but their secondary does make mistakes.
Georgia - 25% I would give us the least chance against them, their DE's are freaky good, could probably play us without adding to the box to stop the run and make the ND offense look as bad as ever.
Miami - 70% Not great on defense so far, lots of near misses for them, their QB would probably look like Caleb Williams last year against ND's defense. Only reason they are still in playoff consideration is ACC officials.
Texas - 50% I don't know why everyone is sold on them being some super team, I think Ewers would get benched against the ND defense. Our offense would be questionable, but if put in good position by the D they should be able to score.
OSU - 50% Can't call it any higher since they should have beaten them last year and didn't, but they should have beaten them last year so no reason they couldn't this year
PSU - 90% Allard might be done, which would mean PSU is done. I'd say 100% but nothing is guaranteed in football.
BYU - Probably the only one I agree with you on overall, they are a good team, but I don't think they would score enough to win.
