41 goals is a lot McNab must have been pretty good is the rep he gets for being soft fair or not?
McNab wasn't physical, he tried to fight once in a while but was remarkably bad at it. He stood out more because of the team. Taz, Jonathan and Wensink may well have been the three toughest players on any team at the same time, the Blues of the early 70's being one if the few examples of another group I can think of.
Add Cashman who made Dale Hunter look warm and fuzzy, Bobby Schmautz who was mean and dirty, Park , who Cherry told not to fight but was still tough and used his stick for more than scoring, Dennis O'Brien who would fight anybody and sadly usually wound up with some bad match ups because given a choice of Taz, Jonathan, Wensink, Park or Cashman guys usually picked Dennis and if you weren't named Jean Ratelle it stood out if you were not aggressively tough. Taking a beating in the slot and not hitting did stand out on that team but McNab usually played with O'Reilly so he really didn't have much to worry about.
