Yes, the comment was made by Geoff. Remember that out of the blue press conference that had Kingsfans panicking back in June (VF21, I think you started the thread)? Well that day, after the press conference, Geoff was on KHTK talking to Napear and Lamb. Lamb asked GP about defense and the rumors of an Artest for Peja trade. Geoff didn't want to get into trade talks (not his thing, his motto is "they're our players until they aren't"), so he replied with the finger, moon proverb.
My first reaction was that it was a swipe at Artest and that he was not down for such a trade. I mentioned in the Griffin thread that it was disappointing to hear such a thing from GP when he's had luck with deals like this before. Kind of a snide comment, I thought. Now that I really think about it, it could be a comment on the people who suggested this trade. But even then it gives you an idea on how GP feels about Artest or at least in relation to Peja.
The way I see it is, the moon relates to defense/winning, and the finger is Artest. You could say it’s an abstract way of saying “missing the point” or not seeing the “big picture”. Artest brings defense, something we need, but he can also hurt us in our quest for a championship with his boneheaded mistakes.
