The Philadelphia Flyers and Montreal Canadiens games always have a certain type of rivalry. Nothing like the Original six days, but ever since the Habs and Flyers met back in the 70's games would usually end up a war.
We also had a good battle in 1996 when the Flyers would visit the Canadiens, with the Flyers leading 6-2 the Canadiens were in a bad mood and were trying to throw their weight around. The Flyers were more then happy because they love the rough stuff too, and this game would get a huge line brawl.
There's hasn't been that much physicality in recent years with the Canadiens and Flyers, more busy trying to rebuild then throw hands, but it would be cool to see another line brawl or goalie vs goalie battle.
