Do you give props to Wisconsin for the encroachment call in the first half, or is that a just a bone-head move on Michigan's part? If I recall correctly, it was 4th and short and Wisconsin lined up in a punt formation, all linemen in a 3 point stance. Michigan kept the D on the field in kind of a goal line formation, but sent one guy back to receive. Then the punter moved under center. He gave a hard count and the entire o-line moved in unison to a 4 point stance, drawing Thompson (and others?) offsides. Maybe that's an old play but I've never seen it before and therefore give props to Wisconsin.
FWIW. Michigan doesn't seem inclined to get re-involved.
