Greatest player of his era, but also the worst GM in the league. Every team he leaves is in shambles
Goddamn this is idiocy. Bron wasn't GM at all for the first run Cavs (and they were just as bad when he got there as when he left), that leaves:
Heat: 4 Finals appearances and 2 rings in 4 years, when he left the starting lineup was solid with Dragic-Wade-Deng-Bosh-Whiteside, that core fell apart due to injuries but they retooled and were back in the Finals 5 years later.
Cavs: 4 Finals appearances and 1 ring in 4 years, last year he was there he didn't get to have a say in any of the trades because they were retooling for the future and they've done a decent job of building back up.
So what team did he leave in shambles? He's literally gotten a ring with every team he's been on, if there was a GM who had built 4 different championship rosters on 3 different squads he'd be in the Hall of Fame on the first ballot. Of course LeBron has a cheat code because he's managed to win rings with deficient rosters, but he's certainly not a "bad" GM. I'd say he's about an average GM, which is pretty fukking amazing because all the others are doing it as a full-time job and for him it's just the side gig.
