He's under contract next season with the Wiz.Unless the Wizards just want to move him as quickly as possible and will take a lesser deal or Beal wants to "poison the well" (which doesn't seem like his style), I doubt the Lakers have the assets for a trade. My guess is that they would have to try to clear the cap space and try to sign him as an FA in the off-season.
