Kind of agree. This is also a game where there is TONS of physical contact. Shannon Sharpe was saying it best on the CBS pregame show. There are a LOT of dirty players that are way worse than Suh in the past, and probably present. Players at the bottom of piles stepping on fingers, poking people in the eyes, stepping on wrists, etc.
It's football. American football. Not lets all sit around in a circle and sing songs together. Players are paid to hit people and make it hurt. To take them out of the game or end their career? No. But a lot of those players who take the field know the dangers. The dude needs to control himself, no doubt, but if I'm his coach I tell him to use that aggression to sack the damn quarterback instead of trying to push some lineman's head into the ground after the whistle is blown.
