+/- stats always have a giant "?" hovering over them for me because they are so team/substitute/rotation dependent. Henson actually probably has one of the worst +/- lines in the entire NBA this year, on both sides of the ball. But that really doesn't pass the eye test. The Bucks best defensive big man by a mile according to +/-? Zaza Pachulia. Now maybe there is something there with him being their only legit NBA big body, so muscle in the post and on the boards. but his defensive +/- dwarfs Sanders'. It dwarfs Marc Gasol's. So is that a clean stat?
Meanwhile Henson charts out at nearly 6pts worse per 100 possessions on defense. Of course Tyson Chandler charts out at nearly +5 himself, so maybe he's in good company.
Here are how our Kings rate in +/- stats, with notes as to likely accuracy:
Derrick Williams
+2.6pts OFF, +7.1pts DEF -- feels exaggerated, but roughly accurate. Good for offense, Lousy defense.
Marcus Thornton
-0.9pts OFF, -4.9pts DEF -- see what I mean? Stats say Thornton is a flat defensive stopper. I say yes he tries, but our alternatives are just awful.
DeMarcus Cousins
+2.6pts OFF, -3.9pts DEF -- probably understates the offensive impact, but defensively likely about right. The old narrative is dead. all we have on defense.
Isaiah Thomas
+6.6pts OFF, -1.6pts DEF -- offense there is the big one, and no surprise. He is our only PG. But defensively again...options this year? Greivis and Jimmer.
Jason Thompson
+2.3pts OFF, -0.4pts DEF -- feels higher than expected on offense, and maybe even slightly understated on defense this year, but solid.
Rudy Gay
+5.9pts OFF, +1.7pts DEF -- juices our offense, but a net negative on defense.
Jimmer Fredette
-1.0pts OFF, +5.5pts DEF -- the -1.0 could = not a PG, or might be replaces IT and plays with scrubs. +/- says defense is still terrible. Does eye test?
Quincy Acy
+1.2pts OFF, +5.5pts DEF -- Do you believe that Acy makes the offense better while is a terrible defender? Maybe because he plays C in place of Cuz?
Ben McLemore
+0.4pts OFF, +5.1pts DEF -- maybe about right? Certainly no coincidence the way he and Thornton's numbers matchup.
You will notice BTW? These sorts of +/- stats suggest that our 5 starters get it done relatively speaking, and its our bench guys who collectively cannot defend and are responsible for our awfulness. Is that really the narrative?
In fact overall +/- suggest:
Cuz +0.0
IT +0.1
Gay +0.3
Thornton -0.1
Thompson -1.1 (weak link, but best option for a 5th)
Actually would be a .500 team if not for their teammates. Is that accurate? Dunno.
Do know this: Henson is a -11.0 per 100 in +/- this season, which doesn't matchup at all with how he's thought of.
