The NBA has never been soft on the integrity of it's referees. You can't even go out and have drinks in NY after the game.
I have to admit I'd hate to be a pro official of any kind. I'm sure your financially rewarded if your good enough, but you must deal with some crap. Some of the more wonderful personalities hating your guts for all time because the Celtics didn't cover the over when they bet their life savings. Fun stuff.
