Tyson Chandler is still a very good rebounder but he doesn't have much impact on defense anymore. More of a neutral defender than a plus defender. Limited offensive game.
Tyson would've been the 3rd/4th string center behind Baynes and Theiss here. The Lakers are more desperate for big man help. He'll offer them more. Give them a useful backup center. Good choice to go there instead of here where he would've played less.
