So I think if Ohio State wins out, they SHOULD be in the Big Ten Championship game.
Undefeated teams are Indiana, Oregon, and Penn State. If Ohio State wins out, that would give losses to Indiana and Penn State. And if the tie-breakers work the way they should, Ohio State would have the tie-breaker over Indiana and Penn State.
1-loss teams Nebraska, Iowa, and *ichigan will work out, too, since Iowa already has a loss to Ohio State, and Nebraska and *ichigan are on Ohio State's schedule, giving them 2 losses.
That just leaves Illinois and Wisconsin to worry about. Illinois has to play at Oregon. That should knock them down to 2 losses.
Wisconsin also has to play Oregon and they also play Penn State. Both are home games for Wisconsin, but I would imagine that we can count on Wisconsin losing one of those.
The only thing that might get goofy is some 3-way tie where we need to worry about coaches' wives' bra size, or something.
