While this is a problem at the offensive end, it is a bigger issue on the defensive side because PER only uses the three defensive stats found in box-scores- defensive rebounds, steals and blocks. We’ve discussed several times in the past that steals and blocks by themselves (without corresponding missed steals and blocks) can be misleading.
The newly tracked NBA hustle stats of contested shots, charges drawn ( a missed charge drawn is similar to a missed steal or block), deflections and loose ball recoveries adds four categories to the three box-score stats for a total of seven criteria. But why stop there? With the aid of video work, one can track whatever other defensive actions are important in each coach’s system. (Please read previous Hoop Coach Article, “Do You Have a System for Evaluating Your Players on Defense?”) Such concepts as defensive containments (stopping the ball on drives), successful secondary rotations, successful hedges, denied cuts, successful transitions, changed shots, and successful closeouts are only a handful of possibilities.
The beauty of this enhanced defensive evaluation is that it is almost totally system based. Players in pressure defense systems will be evaluated differently than players in pack-line and zone defensive systems. Even there, one pressure defense coach will have different teaching points and criteria from another pressure defense coach.
Again, it is your team, your system and your prerogative in setting up your own advanced metrics system.
