LA wants to save 20M dollars (including tax) AND to get an asset for a 33y old guy on a decline who is going to be UFA in 6 months. Good luck with that.
And btw, speaking of tanking, trading Pau would actually make Lakers better, similar how Raptors got better after Gay trade.
Although declining, Pau is still a decent player but he is a terrible fit in D'Antoni' system. He needs the ball in the post and that is a big no-no for D'Antoni. Playing Jordan Hill or Kaman + 4 shooters would make them better IMO.
