I don't recall him saying that, Cal-Kings, and I have to admit to being a pretty rabid Webber fan. In fact, I could just about swear he never said anything of the sort. What he did say was he might return to Sacramento. He wasn't talking about the Kings.
And I don't think we'll see him in a Laker jersey for a variety of reasons. Here are two:
First, the Lakers aren't an immediate contending team. If he did want to go to a Western Conference team, he'd be better served to look to Texas for his best chance at hardware.
Second, the Lakers are rebuilding and looking for the long haul. That pretty much excludes Webber right there. This isn't the Lakers of the era when Malone and Payton tried to score their jewelry.
