The accumulation of on court off court stats that people laugh off but I think it is very telling, if there is one guy who is either way above or way below the metric of the team, IMO, it says a lot.
A player who can average 20 points a game but his team gets murdered on the court and thrives when removed, that is something that happens a ton, and often those players get rewarded with big contracts, despite their flagrantly negative impact. So many NBA teams not figuring out this basic metric is one of the most confusing things in sports. Baseball is an old school game but in the last 30 years teams have developed a pretty good grasp on what stats are worthless and what are not, but the NBA still has teams make horrendous mistakes in judging a players worth.
I know I've beaten him up recently, but Kyle Kuzma is a player that is so terrible he shouldn't even be in the league, but the Bucks are out there, so blind to his putrid play that they not only feature him, but traded away a far better player to acquire him. And this is something that happens over and over.
