The only way the Lakers turns this thing around quickly is if they get rid of LeBron. Word is Jeanie really wanted to trade him and release the Lakers from the hold of Bron/Rich Paul. I know the public stance now is "we're not trading LeBron". But I'm inclined to think that it's because they know no one is willing to give up any real assets for a drama queen star who turns 35 about 1.5 month into next season.
Magic did a horrendous job and Jeanie has no clue about the basketball side of things. People want to give Magic credit for bringing Lebron, but the reality is he was going to LA for Hollywood regardless and the Lakers brand was better for the Lebron brand. He supposedly had 17 TV/movie projects lined up for his production company so there was no way he wasn't going to LA.
The smart thing to do would be to trade Lebron for draft picks and some young players even though they won't be top 5 picks. There is zero chance they can build a contender around LeBron in time because at this age, he plays zero defense, can't shoot and really needs another star to carry the load for the entire season. The problem is that any star who's good enough to carry LBJ is not going to play under his celeb shadow.
Too many stories about LeBron's diva ways have leaked and no real star wants to deal with it and give Lebron the credit if they win. He can still put up stats because it's really easy for him to if he just paces himself and doesn't play defense. It's kind of like when Boogie said something along the lines of "To tell you the truth, it's really easy for me to get 20 & 10 every night if all I want to do is but up numbers".
