Okay, so I'm a nerd... I averaged both schools' stats over 4 common opponents (Maryland, Indiana, Purdue, Nebraska). Couple of caveats, Cook went down in the Maryland game, which may skew their passing numbers a bit. Sparty played 3 of 4 at home while Iowa had 2 of 4. (Forgive the lack of formatting, I don't know how to insert a tab...)
