The Lakers franchise since Jerry Buss died in 2013 has been a pretty big train wreck. First, you had the years where the team served as a vanity project for Kobe has he buried the team with his enormous contract, selfish play, and refusal to stop being the centerpiece of the team. Then they went into a dark rebuilding phase where they actually ended up drafting fairly well (their top picks being D'Angelo Russell, Ingram, Ball and Randle) except that the team never had the patience to wait for those players to develop, and ended up shipping them out to various outposts where they would grow into All-Star level players.
The organization was obviously successful at being able to lure LeBron to LA. I'm not sure how much you can credit ownership or upper management with that; LeBron wanted to go to LA for various reasons, many of which probably didn't have to do with basketball and so he went to the Lakers. That opens the door for the Klutch-inspired Davis trade. They win the title in the bubble, which is becoming an increasingly interesting title to look at when you consider what the Lakers have accomplished outside of that one season.
You can blame a million people; Mitch Kupchak, Rambis, LeBron, Magic Johnson, Frank Vogel, etc. but the common denominator is the Buss family. Jimmy Buss took a ton of flak from the media before handing the job over to Jeannie Buss, who has a much better relationship with the media and has thus skated through a lot of poor administrative decisions. But the ownership is pretty rotten in LA and while the Lakers play by a different set of rules than the rest of NBA teams because they can fuck up things a million times and still remain an attractive destination for players, I'm skeptical on their post-LeBron future.
