If yesterday's performance is a sign of things to come, OSU is right in the thick of it for sure. That said, they're going to need some help.
Bama/Georgia - At least one gets in, and if they're a combined 25-1, they probably both get in. Obviously, SEC chaos would be ideal so they get only one team
Penn State/Iowa/Michigan - OSU will have their chance to knock off each of these teams
Cincy - probably need them to lose one
Oklahoma - need them to lose one, which seems inevitable at this point
Oregon -need them to lose again, and they almost certainly will
Excluding the Big Ten teams, that's 5 teams clearly ahead of OSU right now that we can't pass without them losing. So, we need 2 of Bama/Georgia/Cincy/Oklahoma/Oregon to be eliminated. I like those chances.
