Must know the sport (doesn't matter if you played the game but you realize that you have to put the Ball in the Basket), it is alright if you like defense but need to realize that scoring is part of the game. It's alright that you coach from sideline, but please no demeaning and belittling from the sideline during games. Please don't stall when up by 5 with 3 min. left in game, keep on doing the things that got you the lead. Plus please no bar drinking after game and fighting with fans or non fans, go home and drink all you want.
