Football is a brutal vicious game where lunatics and felons go about trying to kill opponent players. A felonious assault occurs on every play and in a sane world most players would be in prison. To play at the level of NFL physicality one has to have a few screws loose. To expect some semblance of sportsmanship immediately after the gun ends the assaults is just too much IMO. So I don't think its a big deal. Think about it: After the Germans took out most of our warships at Pearl Harbor did we go to Berlin and share some beers with the leaders of the Luftwaffe ?
