Stosh,
Absolutely I try to know certain tendencies of officials. Espeically the ones that I know I better keep my mouth closed
I never say anything to our players about the officials tendencies (this guy lets a lot go so play phsyical, or this official calls a close game so you have to stay out of foul trouble) because I think it takes their focus away from what we are trying to do and focuses it on trying to take advantage of an officials tendencies which is not the best way to win a basketball game.
