Grant Williams is -22 in plus/minus on the season so essentially -1 per game. He is a useful bench player. Nothing wrong with that.
I would caution us about the usefulness of raw +/- numbers, since they tend to reflect the team's net while a player is on the floor. Consider that the Celtics are about a .500 team so far, and Grant is about a .500 +/- player if you look at the raw stat.
The Celtics as a team are +1.6 per game, Grant is about -1 per game. Plus/Minus (nor any other individual stat) is not the end all but is is fairly representative in this case.
We need Grant. He is useful. Not a bad thing.
We have 11 players who have played more than 150 minutes total (call it the core rotation). Of those 11, Grant is the 3rd worst by plus/minus, Pritchard is -38 and Nesmith is -71.
Smart +95
RWill +93
Tatum +68
Brown +52
Schroder +33
JRich +24
Langford +4
Horford -21
GWill -22
Pritch -38
Nesmith -71
The only outlier to me is Horford. He plays a lot with Grant Williams. 212 minutes with Grant, -32. 305 minutes without Grant, +11. Looked at the other way, Grant is +10 when not playing with Horford (241 minutes without Horford). Hmmmm Maybe I am on to something. Maybe Grant and Horford should not be playing together.
212 minutes is about 10 minutes per game and we are giving up 3 pts every game in that time. I admit that plus/minus can be flukey but this is 21 games and a lot of minutes with these two on the court together.
To me, it seems like those Grant/Horford stats say more about Rob Williams than it does about them. If they play together then Rob is on the bench (and the team plays worse), if only one is playing than they might be next to Rob.
Rob's 2nd highest +/- on the team seems to line up with that, too. It'd be interesting to see how much of their +10/+11 comes from playing next to Time Lord.
I think a lot of it stems from the simple fact that Grant Williams should never be starting. He just isn't good enough to be a starting PF. He is fine off the bench, but shouldn't start. And I do think a lot of that - comes from the beginning of games and the 2nd half when Grant has been starting.
