To keep harping on Derozan... his career net +/- numbers are such an anomaly among All- Star caliber players, I had to do a bit of digging:
B-Ref has him at a - 2.1 net +/- per 100 possession for his career, and he's been negative in 13 out of his 15 seasons (he's - 3.2 this season). That just doesn't happen with good players.
In the past 10 years, 61 different players have made an All- Star game. Only 5 of those 61 players have career net plus-minus in the negative: Derozan, Julius Randle at -2.5 (absolutely brutal first three years are dragging him down), Zach LaVine at -3.5 (lol Bulls), D'Angelo Russell at -1.0*, and Jaylen at -0.6*
Only 4 of those 61 have a positive net +/- under 1.0 - Andre Drummond, Vucevic, Brandon Ingram and Dejounte Murray.
Another half dozen are positive but under 2.0- Carmelo, Joakim Noah, Roy Hibbert, Jeff Teague, Goran Dragic, Andrew Wiggins
The guys who are over 8.0 but less than 10 - Duncan, Dirk, Chris Paul, Draymond
Guys over 10.0- Lebron, Steph, Embiid, Jokic
*Looking at the numbers, if guys have negative seasons, it's typically in their first year or two, especially for guys who enter the league young, so the younger guys listed above (Jaylen, LaVine, DAR, Dejounte, Ingram) have had less time for their prime years to bump their numbers up. On the flip side, the numbers tank for guys who play past 35, so Lebron, Dirk, Duncan, CP3 are dinged relative to guys in their prime. Kobe was a significant negative in his first three and last three years.
So Derozan really is a huge outlier. If he's good, why are his teams almost always better when he doesn't play? I'll also note that he's been horrible in the playoffs- Has a career playoff TS% of 50.4, and his net +/- drops way down to - 11.0 (!!!). All that reads to me as a guy who's all sizzle no steak. Still, given his counting stats and accolades, he has a decent chance at the Hall of Fame. I wonder if there's any HoFers who's teams were better with them off the court.
Edit- whoops, left out this year, which adds Brunson and Scottie Barnes to the "slightly positive" list, and Banchero's a big negative, albeit still just 21.
