In terms of total athletic department revenue, Ohio State came in at #3 overall, Michigan #5, Penn State #6, Wisconsin #10, Iowa #13, MSU #16, and Minnesota #23 (Nebraska comes in at #21). That Big Ten Network money sure does a lot for revenues.

Interesting that the distribution of revenue is pretty equal between the two divisions for next year:

Ohio State's division: $39,637,570
Michigan's division: $43,960,182
