Some friends and I were curious about the last time the Lions and Michigan had gone this far into their respective seasons undefeated. The Lions haven't gone 4-0 since 1980. I emailed Greg Dooley (MVictors) this morning and asked what he thought. His response was that he doesn't think it's ever happened, and the closest he could think of was in 1970 when the Lions went 3-0 and Michigan was 9-0.
Just thought this was an interesting bit of information to share. Here's to a couple excellent seasons for both teams, and Go Blue!
