As fans we're allowed to lose our nut at the refs from the comfort of our loungerooms (especially if we're a few sheets to the wind

). It's like yelling at them when you're at the Garden, safe in the knowledge that they can't hear you

But it's disappointing for a player and coach to lose composure to the point where our game went to pieces after it. I just don't think that's the greatest mental strength displayed. I thought Joe was all about controlling the controllables, and the referees are about as big a "uncontrollable" as there is, after maybe the weather (for football games).
Anyone gets frustrated and anyone can get T'd up, especially in the face of unfairness or incompetence. I also get it when coaches strategically get Td up to stand up for their guys. But you can't let it affect how you play. You've got to be able to regroup. If you can't then you have to learn to control your emotions.
The saving grace is that it happened in a meaningless regular season game, against a team that we won't see in the playoffs. Imagine if it happened in the NBA finals - they get a bad call, they get Td up, it changes the momentum of the game, they lose the game. They'd be kicking themselves.
