The problem is that you're conflating ability with production. These graphs don't tell a player anything other than what they would already know from reading a box score. All you're doing is recontextualizing them into a number which doesn't have any intrinsic meaning.
Man, I gotta say this looks like GIGO to me. Analylizing ballhandling/defense with box score data? What sort of box score data reflects basketball IQ? Seems like a fools errand. And the scoring analysis...he can look at the box score and figure that out.
