The Vancouver Canucks may be punching above their weight class in the early season, but their penalty kill has been very good. As of writing, they currently hold the eighth best PK in the league, holding at 86.4%. However, that notable spot could be in trouble with the recent wave of injuries.
J.D. Burke beat me to the punch, covering the Canucks penalty kill at the end of his new edition of the Mathletties. This is behind a paywall, but I will try my best to not cover exactly what he addressed.
So, if we want to figure out which regular penalty killers are good or bad, we need a way to tangibly compare them.
