So I was curious how each team in the B1G was doing Home vs Away, and decided to do a quick compilation of some data. Here are resulting charts (H means home team won, A means away team won, N means that game does not happen, and U means it's an upcoming game still):
And a chart with just the records by team:
As most of us are aware, Michigan is the only team with a perfect record at home in the B1G so far this year. For as bad as Michigan has played on the road this year, Minnesota has the biggest difference in win percentage for home/road games. Michigan comes in at #2, and Iowa at #3.
The average B1G team wins 64% of their home games to just 36% of their away games. I'd be curious to see how that compares to other conferences, but I'm too lazy right now to try to dig up the data for that.
