For me 2006 OSU vs Michigan. Anytime I stumble upon anything relating to it I end up having to watch highlights to torture myself again. I remember every single event i did during that game. From the feeling that we were going to lose when I went down high st for halftime dinner. To the late hit Crable delivered and how even if it didnt happen it felt like the 2004 rosebowl where there was no stopping the QB only hope of messing up. Any how what event would you change in Michigan history and it has to be a single event. Be it something like a game you wish we won, or wishing drew henson did not leave to play baseball.
