At Thompson being ranked in the top 20. He's the most overrated player I can remember in the 20 years I've followed the league, a glorified role player who's got the cushiest job of all time for a supposed star. On most teams, he'd be exposed as nothing more than a better offense, worse defense version of Danny Green.
Aldridge, as underwhelming as he was and as much criticism as he received, still outpaced Thompson in most significant advanced stats.
They've tried to dissuade the best players from congregating, but they can't literally stop them if they're determined enough. Even before this trend, they never had parity because it's not possible in a sport with 5 players per team playing at once, more possessions/scoring chances than any other and no goaltender/pitcher to serve as an equalizer of sorts. Superior talent is almost always going to win out.
