Sorry. I think the Broad Street Bullies created and perpetuated the need for the "enforcers" to keep the guys who actually played hockey out there from getting cheapshots from goons like the 76 flyers. IMO, they hurt the game in the long run.
Don't get me wrong, I have no problem with fighting in hockey. Its an integral part of the Canadian/American tradition. I love to see two evenly matched guys drop the gloves, even better if they are skill guys. But having goons that can hardly skate and only exist to beat people up is not what hockey should be about.
If you want to watch a good documentary on it, there is a show called The Last Gladiator that is basically the story of Chris Nilan's life. It has interviews with Bob Probert, Tony Twist, and a bunch of other goons, only some of whom had any real hockey skills beyond knuckles that dragged.
