Let’s also the. add John Ogrodnick, Rick Kehoe, Mike Bullard, Charlie Simmer, Al Secord, Guy Chouinard, Danny Gare, Jacques Richard, Wayne Babych, Hakan Loob, Dennis Maruk, Brian Bellows, Pierre Larouche, Blaine Stoughton, Stephane Richer. They scored 50 as well and some multiple times.
Many guys scored 50 goals in the bloated goal scoring era of the late 70s and 1980s. Many of those above on not very good teams. Scoring 50 at that time was nothing hall worthy in itself.
You can’t compare stats from the 1980s to the 2000s and 2010s. Team scoring was 40% higher in many of those years.
