The Lakers make sense on a lot of fronts. The question to me is not whether LeBron will go to the Lakers or not but who else will go. Chris Paul? Paul George? DeMarcus Cousins? Instant contender.
If this really is about family (and I don't doubt that it is), why would the James family want to move to Boston or Houston or Philly?
The Lakers only have $39M committed for next season (excluding draft picks) and Deng accounts for $18M of that (what a bad deal). I suppose that Deng could be stretched or maybe traded by including him with a desirable prospect to a team with cap space. It would be like trading Deng + Prospect for Chris Paul.
