I'm too lazy to find a link, but anyone who's been watching ESPN today has probably seen this. Apparently he wants a trade, but his agent is saying anything. I don't really know why he'd want traded, because he's not going to get sent to another contender, at least in all likelihood, and I doubt he sees his production go up too much (if that's really his big issue).
And now, as I was looking for a link, I find an LA Times blog stating that he doesn't want to be traded. Well ok then. Source
