Punishment: Ejected from game, 2-game suspension
Football is a violent game, and as such we have to adjust the barometer for "unsportsmanlike acts" to account for the fact that players are naturally going to brutalize each other. However, when the whistle blows and the piles are separated, usually civility wins out. Ndamukong Suh, a player notorious for his particularly rough style of play, doesn't subscribe to that practice. When he ended up on top of the Packers' Evan Dietrich-Smith, he decided that instead of simply getting up, he'd slam his opponent's head into the ground three times and then stomp on him for good measure. A truly classy move, and one he decided to do on Thanksgiving of all days.
