Any fan who pays enough attention to the NHL knows that the league has had a long-standing problem with the way the game is officiated.
Bad calls and consistently getting decisions wrong are not problems unique to the NHL. Each major North American sport has both similar and unique issues to their own league. The NFL has pass interference, MLB has the strike zone and the unique superseding powers umpires are granted, and it can sometimes appear arbitrary what would constitute a technical foul in the NBA. Even here in Europe, VAR has turned the Premier League into a “spot the difference” game with the millimeter offsides decisions tainting the game across the continent.
