Statistically Determining Defense

[dirkfansince1998]

You know what's insane, statically Luka is a great wing defender.  Luka's 3ptDfg% and missed 3ptrs is premiere.  The more I analyze, the more I think Kidd is an awful coach. We had all the components other than rebounding to be elite last year.

There will always be stuff the numbers cannot tell us. How many rotations did Luka miss. How many times did he not close out on a shooter. How many times did he not get back on defense.
I guess one could argue that the sum of all of it is +/- but even regressions in large sample sizes like 5-year RAPM cannot completly reduce "randomness".

In a way that is what the C.Wood debate comes down to. A player that is looking good if we are just looking at counting stats or tracking data. But where do I find the stat that tells me how many times Sweeney had to call out defensive assignments or rotations because even 60 games into the season he still didn´t know the scheme.
