Yeah, I think this is just regurgitating year+ old rumors about the C's and Gasol. Unless they are going to trade Pierce or KG, the numbers just don't really work.
I do disagree with the notion that Gasol doesn't have a lot of value. Yes, his contract does make it tougher for teams to match, but that is a hurdle that can be jumped by many teams in the league.
Now, the Lakers may value Gasol more than other teams do, which would be an issue. But I expect if Gasol is traded, it will be for a pretty significant haul.
