Park was a terrific player but even when he was the NHL’s second best defenseman there was a significant gap between him and Bobby Orr. Like a Gretzky to Trottier, Clarke, Yzerman whoever gap. Orr was just the best…..no ifs, ands or buts. Looking at that era then as Orr was going out because of injuries Potvin and Robinson were coming in and both of them fairly quickly supplanted Park as better players. I don’t think there was ever a time when Park was the best D in the league. He was always in the top 10 and often in the top 2 to 5 throughout his career. That makes for an easy call on putting him in the Hall of Fame but it also kind of explains why he never won a Stanley Cup when you consider Orr, Potvin and that Montreal had the best goalie Ken Dryden and regularly dressed 3 future HOF’ers (Robinson, Lapointe, Savard) night after night, year after year on their D.
