When you think of the Philadelphia Flyers, the first thing that comes to mind is a physical, gritty style of play. A style of hockey that emphasizes aggressive play, like hitting and getting into fights, to intimidate opponents and gain the advantage. But the Flyers are not the only team to do this. Every NHL team implements this strategy in some way or another, whether it be one line or the entire roster.
The reason this style of play is so closely associated with the Flyers is the legacy of the "Broad Street Bullies". The closest thing the NHL will get to a team like the Danbury Trashers, the early 70s Flyers achieved sustained success built on aggressive physical play.
