Bit unfair to generalise tbh, I'd imagine most of them play for love of the game. It's a very physical sport, as is rugby, and that's the risk you put yourself at. Can completely understand that mentality and even some of the more cynical things you see them doing in the course of play.
Of course, there's no excuse for what you see there, that's absolutely cynical and occurs after the play too.
Best player in the NFL and everything, Haynesworth.
Free Agent this off-season, likely to get a deal worth about 10 million per year. Isn't life fair?

Detestable thing to do, could have blinded Gurode had it been a few inches difference in the stomp. Horrible scumbag of a player.
That said, I'd love to have him in Denver.
