What I find important and what could be clearly defined and well-charted as well, are “disruptions” (?), where the defender deflects a ball out of bounds or somewhere into the field, forcing the opposing team to reset the offense (but no direct turnover).

The steals and blocks specifications all make sense and should be easy to chart, no complaints. But they’re not that ground-breaking, imo.

PPP on post ups are imo interesting, what I’d also be interested in is how many times coach sends a second defender to double team. On the other hand … would that already be too specific? After all we’re not charting that on the offensive end either.
