Fixed it for ya!
I actually preferred the earlier rival with the Rangers and Bruins because my cousins were Ranger fans, but the Flyers and Bruins went at it pretty good.
Two days ago was the 30th anniversary of the brawl in NY, where the Bruins climbed into the stands and went after the Ranger fans who had been harassing them. I'll never forget O'Reilly leading the charge and Peter McNabb taking a shoe off a guy's foot and beating him over the head with it.
Those were the days.
