I’m too young for the great habs/bruins rivalries of the 70s, but Edwards sure brought out my hate for your team, its not the same without those types of guys, having players/personnel you truly hate always made for better games.
That is precisely why I appreciate the likes of Edwards and Marchand -- people who are good at their job and also get under the skin. You mention the 70s. That was my favorite decade of the NHL partially because there were so many villains that helped stoke the hate between rivals.
A good amount of soul has been leaving the NHL as cookie cutter announcers dominate the booth, expansion has led to rivals not playing each other as much, and bro culture among the players has replaced much of the hate.
It always saddens me a little bit when an announcer, coach, or player who served as a lightning rod retires, because I know nowadays they will likely be replaced by someone whose public image is based around promoting their "brand" and who will not be as entertaining.
Edwards spouting nonsense comparing a hockey performance with the American Revolution was far more entertaining than the soul-less drivel of announcers bantering about their golf scores at the latest charity golf tournament or what the current betting odds heading into the 3rd period are.
