I think you can look up to KG and not have to defend yourself about it at all.
If the worst thing that people can say about KG is that he has said some mean things on the court, takes the occasional cheapshot while playing, and has gotten into with teammates, then you are describing every great player that has ever played the game.
I wish they would record the audio of every player that plays any sport at any level, and you honestly tell me that the type of talk that KG does is any worse than anything else that is being said. It's trash talk, and that's it. I metaphorically compare it to a comedian making jokes during his job. Some jokes are very un-PC but it does not necessarily mean that the person feels that way.
People want to say KG is fake tough, and then they go crying to the media when he says something mean to them on the court. Give me a break. It happens in all sports...everywhere. Guys like Carmelo and Villanueva are just being baby's when they take that stuff off the court. If you are upset about it during the game, do something about it. Win the game. Talk back. Fight back. But don't take it off the court.
KG is a good guy and a good person. He has never had any off court issues, is a good family guy, and comes to work everyday. All the other chatter that people say about him is no more significant than anything that is ever said on a basketball court.
