Nicknamed "the Hammer",[1] Schultz is renowned as one of hockey's best enforcers and holds the NHL record for most penalty minutes in a single season, at 472.

[3] After winning two Stanley Cups with the Flyers (1973–74 and 1974–75), "the Hammer" drifted through several teams (Pittsburgh Penguins, Los Angeles Kings and Buffalo Sabres) in search of a permanent position.

Soon after this trick became popular, both the WHA and NHL passed what became known as the "Schultz Rule" — thus banning the boxing wraps' temporary involvement in professional ice hockey.

[8] After retiring as a player Schultz coached several minor league teams over the next two decades including the Madison Monsters, Baton Rouge Kingfish, and most recently the Elmira Jackals.

[9] Schultz co-authored a book entitled The Hammer with Stan Fischler[10] that provides insights into the world of a professional ice hockey enforcer.
