I watched that Wisconsin TD over and over, screaming at the TV. OSU had a defender out there with a good shot a taking him short of the TD (and first down), only he was pushed down from behind (blatantly might I add). Am I missing something or shouldn't that have been a blocking in the back call on Wisconsin??? With the way NO ONE mentioned it on the TV or in print that I can see, maybe I do not understand the rules properly.
