I personally have no issues with what they do. I love Justin Williams, especially when he was with Washington. He just gets it. They are grown men who get payed very well to play a game for a living. It's supposed to be fun and entertaining. They aren't doing it while the team is still on the ice, or when they lose. They wait until the other team leaves and they entertain the fans with the fun and joy that a win brings.
The old guard is just that, old. The league is only getting younger.
