Yeah, I don't disagree with any of that. But I also think that, again, you have to take what Klay and Kerr said in context--which was, again, just a short response to reporters asking them about it. They didn't go on some long rant. Basically just gave a 3 second answer and moved on to the next thing.
Honestly, I think Draymond responded better. He basically laughed it off and said, "That's playoff basketball. I've heard worse." (that was on his show, anyway; I didn't see any clips of him responding to the media asking about it, although I'm sure they must have if he talked about it on his show later last night)
Anyhow, this is a pretty good series. I wouldn't have complained at all if the Warriors swept the Celtics and won by 40 points every night. Other than Boston fans and advertisers, I think everyone in the country would have loved that. But it's fan that they are trading haymakers with each other too. Boston has definitely stepped it up from what I saw in the Miami series. It'll be interesting to see what happens if the Warriors tie it up on Friday and come back to SF with it becoming a best of 3 series.
