Wisconsin dominated us on the run so it opened up passing for them because they had the luxury of running or passing at will. They also weren't pressed to score so it made it unpredictable and had the Defense always worried about the run.
I said this before. Detmer is predictable and calls plays based on the situation instead of dictating to the defense. He only runs RB plays up the middle (no off tackle) almost never attacks the flats and almost always simply chooses to go deep on 3rd and long instead of doing a screen or draw. This is as predictable as it gets.
