Dave Schultz was drafted in the 1969 Draft out of Sorel from the old Montreal Metropolitan League. He was NOT very tough in junior. Kevin Morrison, playing for St.Jerome gave him a beating - afterwards Schultz did not want to fight him again. Also a Rosemount player did a number on Schultz.People who followed the league were surprised how he was perceived in the NHL
All-time PIM's is more a tribute to longevity - a function of hockey and fighting skills and being a team player.
From my perspective Steve Durbano, Bob Kelly and Andre Dupont were tougher. Durbano had no concept of discipline whereas Kelly and Dupont were not willing to brawl game in game out.
