Why do people keep bitching about Kevin Garnett?

I will admit i'm a Lakers fan but i love KG and i respect his game. Why? Because he plays the game with a pion and gets the job done.I hate the Celtics more than any other team, not just because of the rivalry,i hate them because i know as long as KG is on their team they have a shot at the title. Plus, if players have a problem with his antics, do something! Whining is not a good trait for people to have!
