Worse Player - Horace Grant >.< (He's old) Worst Attitude - Ron Artest Artest really doesn't have sportsmanship.
I just want to state one thing. To be in the NBA is quite an accomplishment! You are playing basketball at the highest level, with the world's best basketball players! None of these players are bad, the "worst" player would destory anyone here on a basketball court, irrespective to how good people may think they are. That being said, I really am not sure as I don't pay attention to players who don't get court time. Hmm ....... Zendon Hamilton ?? I think he struggles against NBA players, even though he'll whoop my butt in a game.
