I had a rule when I was on the bench.
No matter how the officiating was, I shut my mouth when my club wasn't giving competitive effort.
This team is not competing - at all - defensively. That's the problem.
Or perhaps we could start a concurrent game thread: "Referee complaining: Celtics vs. Magic."
Until this team makes even a half-hearted effort to defend and execute, I'm not going to worry about the officiating.
