Yeah, this 'Code' is fucking bunk.

"Throughout the 1980’s there is no reference to “The Code” that I could find in any player interview, game summary or sports article.  I managed to find “hockey” and “code of conduct” in several links but they were descriptions of rules that would be the opposite of what I was looking for – rules that banned fighting and dirty play in the sport.  During the 80’s, a period that could be defined as the glory years for enforcers, I could find no mention of unwritten rules or “The Code”"

My thoughts exactly.
