The topic that will always generate the least consensus in hockey is that of officiating. Calls are inconsistent, referees don't act the same way, and star players seem to be less targeted.
However, when a rule is clearly stated, and referees make a contradictory decision, it becomes quite embarrassing.
In the game between the Canadiens and the Stars, Jake Evans received a four-minute penalty for high-sticking. According to the rules, the player must be bleeding for it to be called that way.
However, Joe Pavelski was not bleeding, and yet Evans still received a four-minute penalty. When your team is trailing 3-2 in the third period, the difference between two and four minutes in the penalty box is enormous.
Indeed, it is difficult to understand. The inconsistency in officiating has once again made the NHL look ridiculous. When penalties are a matter of judgment, like interference, for example, it's understandable. But here, it's total incomprehension.
