Now have a relatively definitive answer on the penalty minute thing. Based on the obscurity of this, I'm pretty sure this is the only time in the last 31 years that this has ever come up.
I put “officially” in quotation marks because it reminded of a story that is relevant to all of this, about a project I did for the Elias Sports Bureau a long time ago. During the first meeting, a supervisor came in and reminded us that although accuracy is a primary goal, it should be noted that “official” is NOT a synonym for “accurate”. He then quoted the derivation of official being from some Latin word meaning “of the office”. The point of all this was that in the end “official record” or “official stats” means whatever the office says happened, not necessarily what actually happened. So officially, Nieuwendyk (or Ramage) never high sticked anybody and was never penalized. And officially, the Whalers scored a power play goal, regardless of whether it really happened or not. Because the office says so.
