I know the reffing thing is tired at this point, but I just took a look at the net penalties per 60 out of curiosity, and it’s unsurprising to say the least.
Regular season highest net penalties / 60 mins:
Buffalo at 0.53.
LA this series is at 2.18. The next highest team is at 1.33.
LA in our regular season series was at +1.25. So despite the playoffs being “when the whistles go away”, and the oilers being right around even over the entire regular season for net penalties, the kings are getting twice as many pp opportunities per game against Edmonton than they did in the regular season matchup, which was already quite high at +1.25.
