On Reddit they were discussing how if there was to be a “random” COVID outbreak to prevent this game from being played and both teams won out, IU would hold the tiebreaker due to the record of out of division opponents and go to Indy. :D If Northwestern beats Purdue today, they could have a random COVID outbreak to cancel their game with Wisconsin, making Wisconsin ineligible for the Big Ten title game, then would finish their season with games against Minnesota, MSU and Illinois. And they’d only need to win 2 out of those 3, or 1 out of 3 assuming IU(or somebody else) beats Purdue
