If the Big Ten didn’t have divisions, Ohio State wouldn’t have had to wait a year for a shot at revenge against Michigan following November's rivalry loss.
Since Ohio State and Michigan were the only Big Ten teams that finished the 2021 season with one loss in conference play, the Buckeyes and Wolverines would have played again just one week later in the Big Ten Championship Game.
If you’re a traditionalist, the idea of Ohio State playing Michigan in back-to-back weeks instead of just once a year might seem like sacrilege, but that might soon become a real possibility.
