Michigan and Ohio State have had three common opponents this season. Here are the YPP (Yards Per Play) in those games

Michigan 6.1, Washington 4.5
Ohio St 5.8, Washington 4.4

Michigan 7.2, Wisconsin 4.4
Ohio St 7.0, Wisconsin 3.1

Michigan 6.5, Purdue 4.2
Ohio St 6.2, Purdue 4.2

Does this mean anything? Not sure! But I still found it interesting...
