Statistically Determining Defense

[Ghost of Podkolzin]

Only thing I can see is the weight of missed 3’s being really high. What is your justification for that?

Sorry.  There were some type-os.  Corrected.

8% -- Paint-Dfg%
19% -- Paint-Missed FGs
6% -- Mid-Dfg%
13% -- Mid-Missed FGs
3% -- 3pt-Dfg%
11% -- 3pt-Missed FGs
6% -- Defensive Loose Balls Gained
2% -- Charges Drawn
7% -- Defensive Box-outs Resulting in Team RB
17% -- Defensive Rebounds
6% -- Blocks
2% -- Steals

So, looking at that specific weight, I'm putting 43% of the overall weight on # of FGs missed.  Looking at that piece, the 3 ranges break down as follows:
Paint - 44%
Mid - 30%
3pt - 26%

In today's NBA of centers having to switch on defense and guard stretch bigs, I'm happy with this weighting.  What are your thoughts?
