My father went to UofM and is currently on faculty at MSU, heading up the survey research office. He grew up in the U.P. and spent much of his youth playing hockey (I might add he, still plays, in an over 30 league). Many of my family members have played for various colleges and semi-pro teams, so he's fairly well versed in what is and isn't acceptable in hockey.
He is currently working on a project for the MSU athletic department regarding sportsmanship in the student body.
He wasn't watching the game, but I told him what happened.
He has a meeting with the AD in the next week or so, and I asked him if he'd talk to the AD about it. I'm looking forward to what he says. I'll relay it here.
