While Jak, Josh and Doug may not be the targets the Lakers almost have to trade Westbrook for some tradeable pieces to prepare for next year. By trading for RH they have signaled their intention to not create cap space next year, but to work over the cap. Keeping Westbrook would be a huge liability going into next season because no one is going to want to do a sign and trade for him that would bring back the kind of players the Lakers need. So unless they plan to re-sign WB to a cap-friendly deal I just don't see a path to improvement for them.
