So, interesting tid bit
If PSU, Michigan and OSU all end up 11-1 and the losses for each team is one of the other two, it will lead to a 3 way tie. One of the tiebreakers is
the combined wins of the three teams from the other division. So, having Iowa go 11-1, coupled with Illinois winning 7-9 games and being bowl eligible would be advantageous for PSU (you can assume Northwestern will not win very many games this year).
Michigan's 3 opponents - Nebraska, Minnesota and Purdue
Ohio State's 3 opponents - Purdue, Wisconsin, Minnesota
