Then I think you missed it. Suh hasn't done anything to be suspended for a game since he's been with Miami I don't believe. He may have been fined a time or 2 but this went well beyond that. This isn't the first offense for Gronk either, he's been fined a couple times in the past as well. Suh has tried to clean up his dirty image since he's been with Miami. He's done some borderline dirty things while with Miami, but nothing that compares to what Gronk did in that game.
A Patriots homer isn't going to see it that way, even though that is reality. Gronk can do no wrong!(unless he's dancing in the club when he has an injury or cheap shotting a rookie). Brady can do no wrong!(unless he's deflating footballs or cheating on his baby mama).
