And by game management you mean making calls based on the score, or balance of previous calls, rather than on merit? That’s a huge problem!
As much as I hate the league I actually don’t think it’s malicious here. I think it’s just incompetent. Compare it to baseball where home plate umpires used to have pet strike zones, like their own little brand or something. MLB didn’t want it that way, they just didn’t give a shit. Eventually people got so fed up with it that they instituted the reviews they have now. They don’t have any automation, but they DO get their calls reviewed after the game. The pet strike zones are gone. Players will still argue a call, but you don’t see the broad frustration there is with the NHL.
What this ignores is that many calls are marginal. At what point does a hook become egregious enough to call? What about a trip? I don’t want every marginal infraction to get called, I just want a consistent standard that isn’t affected by score or prior calls.
