The Lakers are going to be a very bad team. I mean Lopez is now by far their best player and we know what teams with Lopez as their best player look like. Even if Ball is the second coming, they still won't be very good. I mean even the very best rookies of all time, guys like Lebron James, Michael Jordan, etc. only increased the win total of their team by like 15 games and Ball isn't going to be one of those guys and they lost a bunch of key contributors from last year's team (Williams, Russell, Young, Mozgov) while really only adding Lopez and Ball.
I wouldn't be overly surprised if the Lakers finished with the worst record, though would expect the Nets to be worse and the Lakers to be in the same general range as the Suns, Kings, and the Knicks (if they move Anthony and/or Zinger). If George or Butler get moved, the Pacers and Bulls could certainly fall off the map, but that might elevate a team like the Suns (if they acquire Love and send assets to the other team).
