Teams that lost a playoff game that could've won the title

I was thinking recently about the 2022 UGA/OSU peach bowl and how phenomenal of a game it was, and how incredible OSU played despite the loss. I think everyone pretty much knows that OSU would have easily throttled TCU in the title game. Got me thinking about other cases where a team lost a playoff game but likely could've/would've won the title had they made it.

This one is a LOT more iffy, but I also rewatched the 2017 rose bowl recently and I think OU would've likely beaten bama for the title that year. OU's defense was mediocre and not near as good as UGA's obviously, but their offense was hell on wheels. They put up insane numbers that year including putting up 48 on us that game. Baker Mayfield and kyler murray, Cedee lamb, Mark andrews, etc. They definitely would've scored on bama but likewise would've given up points too. The key variable, to me, is that in this scenario jalen hurts doens't get pulled at halftime for utter and complete incompetence like he did against us. In other words Tua (and najee and some of the other TFr that were inserted due to no other choice) don't play as much either. With hurts playing the full game I have to think OU wins in a high scoring shootout.

Can y'all think of any other such examples? Doesn't need to necessarily be limited to playoffs either, although I guess it'd be a harder exercise using older formats.
