I live in Michigan and I am a "homer" in every sport except the NFL. Michigan State, Tigers, Pistons and obviosly the Redwings are
my teams. The only reason that the Lions aren't my NFL team goes back to childhood and a silly Super Bowl bet I made with my Dad when I was seven. He told me to pick a team and if they won I would win a candy bar. I picked the team with the star on their helmets, they won and for better or worse, I've been a Cowboys fan ever since. No matter what I want to see my "local" teams do well, even the Lions.
Michigan State can tell you about "rioting" after a big game.
Actually I think they offer a course if I'm not mistaken.
