@ArponBasu : Stephane Richer's 50 goals in 1987-88 were tied for 6th in the NHL. Max Pacioretty, again, is currently fourth. In 1989-90 Stephane Richer had 51 goals. He was tied for seventh in the NHL.
That was back in the day when 50 goal scorers were much more common than today. It was still a great feat but more common back then. A guy who hit 50 could still have 5-10+ players ahead of him on the goals list.
