Hypothetical time!
Let’s say Oregon, Penn State, and Indiana all win out (yes, that would entail PSU beating Ohio this weekend, and Indiana winning at Columbus). But let’s say they do. That would lead to the 4th tie breaker to see who goes to Big 10 championship game, which is this: “The tied teams will be compared based on the best cumulative conference winning percentage of all conference opponents.”
Does the committee keep out a closer loser in the Big10 championship and/or an undefeated team that didn’t make the game because of a 4th tiebreaker?
