When I first heard about it, I was thinking that it was just another Celtic player being a D Bag.
But after hearing Kenny Smith and Greg Anthony explain it, they're right. You're playing basketball...what's said between the two players is between them.
There is no crossing the line when you're talking trash...that's why it's called trash talk. If it hurts your feelings, elbow him in the gut the next trip down the court.
KG can say whatever he wants on the court. Charlie V should have punched KG in the mouth if he wanted to send a message.
Bringing it to the public looking for sympathy or trying to expose KG is not right. What's said on the court stays on the court.
As to the topic, Hell no, KG shouldn't apologize.
