7. Kevin Garnett, Boston Celtics
He's so damn intense. KG really needs to chill out a bit. Fans on opposing teams hate him as well as players. Garnett drops f-bombs like they're going out of style and he'll throw a vicious elbow while saying one. He also likes to get under your favorite player's skin by calling them a motherfucker and then hitting them in the nuts. "The Kid" has turned into the "Angry Old Man."
