Well, Chamberlain was traded to the Lakers (I assume he demanded it, but it's mostly because Los Angeles could afford to pay a fuckton of money)
Abdul-Jabbar was traded for as well, but I don't know the story behind that.
I don't really consider Malone to be a Laker, but that was a weird situation of a team that looked like it could win but desperately needed something so a player took a last ditch chance to win by jumping on board. I'd have to think who else he could have signed with. Detroit, Sacramento, and San Antonio had big men. Maybe the Nets or the Celtics would have worked, but the team with Phil Jackson seemed like the smarter bet. Also, in the absence of Shaq, the Lakers had greater need.
So, aside from big pockets and well-timed good fortune, I'm not sure what it says.
