The Philadelphia Flyers Broad Street Bullies logo started out as a Mitchell & Ness and New Era collab (MN designed the logo) around 2002.  The logo itself is a ode to Dave Schultz (the red hair) also in the old 70's jersey with old style gloves a black eye and the tape hanging off the stick just classic... back of the cap has broad street bullies arched above the flyers logo.
