As a Patriots fan, it's convenient that I think the sign stealing stuff is overstated. I think coaches are doing all sorts of stuff that goes unreported. Once someone is caught crossing the line, they become immoral and indecent compared to the other good-Samaritans in football. I think this stuff is kind of nuanced, and I hesitate to hammer Michigan until we know more.
Would it be immoral for a wealthy booster to travel at his expense, purchasing two tickets per game and documenting signs? I always assume that everything that happens on the field can be captured by video. That's why they have locker rooms.
