One thing about this playoff and Ohio State is just how much of a do-over this whole thing is.
Oregon beat Boise St. which due to weak OOC Big 10 scheduling was probably the best OOC win the conference had. They then went on to beat Ohio State and Penn State. They're undefeated. What's their reward? They get to play a super talented two loss Ohio State team, who even if they beat them is still only 1-1 against them with one more loss.
An 11-2 team is playing a 13-0 team
that already beat them and this game is the one that counts because playoff games are magical. Ohio State can absolutely blow up their bracket and furthermore I would argue this is one reason some people might have wanted Alabama out, because if they got hot they could have done the same thing.
Here's a model someone did showing the chaos Alabama would have introduced to their bracket, dramatically reducing some team's odds of progression:

The regular season just doesn't matter that much and the talented teams that sneaks in can do a lot of damage...
