I know that every Michigan fan considers OSU to be the biggest rival but I think it's time for MSU to be held in the same regard. They are a bunch of thugs that are coached to do anything possible to gain an advantage over Michigan.
Say what you want about morals, but sometimes you do have to play down to your enemies level. I do not condone William Gholston-esque style of football. Michigan State was a zillion times more aggressive in this game because they absolutely hate Michigan. I don't feel like the hate is reciprocal. Obviously Brady Hoke and Company want to beat MSU but until the aggressive nature of this game is met by the Wolverines in a professional manner, the Spartans will keep having their way in this rivalry.
