Crawford is universally disliked by everyone.
But, Crawford has a long history with Tim Duncan and the Spurs. He once threw Duncan out of a game just for laughing. I repeat a professional NBA referee threw a player out of the game for laughing on the bench. Not fighting, not a flagrant foul, not cursing him out, but just for laughing.
This is the guy who is in charge of Game 2 of Spurs vs. Heat. You have been warned.
