Years ago, when rebound percentages were still seen as newfangled, the first question I was ever asked by a Division I coach was what the best target numbers are for both offensive and defensive rebound rates. I don’t remember my response, though I would guess I delivered, as requested (I was thrilled simply to have had my opinion solicited), two numbers spelling out what the team “should” be doing.
I now think that was a mistake. True, thanks to Dean Oliver, we know that the four factors in basketball are shooting, turnovers, rebounds, and free throws, and we rank offenses and defenses on each of those metrics.
