Here are some numbers I find interesting:
The good:
Smart +96
Brown +94
Tatum +91
Freedom +59
Schroder +47
Richardson +40
RWilliams +39
The midling:
GWilliams +5
Horford -2
Parker -7
The Ugly:
Fernando -37
JHern: -40
Nesmith -46
Pritchard -51
Langford -55
I find it interesting and telling how these +/- totals are stratifying. It is a good sign that our best players who get the most minutes are in the "good" category. The outliers are Freedom and Horford. It is also surprising how bad the numbers are in relatively few minutes for some of our deeper bench although Nesmith, Pritchard, and Langford are 3 players that we need something from but the results have been really bad.
I know, +/- can be distorted for an individual player by a whole host of things but this is a fairly large sample of games allowing for a large number of line up combinations. The Celtics have played 37 games and Nesmith, Pritchard, and Langford have all played in around 30 of them.
In total, these 3 have accounted for a cumulative -152 or about -5 per game. Bruno and JHern have done their damage in far fewer games and minutes.
