Doc Rivers has been perhaps the loudest coach in proclaiming the irrelevancy of the offensive glass:
“So, you’re a big believer in offensive rebounds I think; I’m not. Listen, like I said, you can pick on that all I want. That is a number I rarely look at, is offensive rebounds. Statistically it holds up. I can tell you, you don’t offensive rebound, you stop transition, you win more games than when you get offensive rebounds. I can guarantee you that on those stats.”
But he’s far from the only one. The Spurs under Gregg Popovich have long punted on offensive rebounding out of the same belief, and several of the most successful teams in recent NBA history — Rivers's Celtics, Stan Van Gundy's Magic, Mike Brown's Cavaliers (to a lesser extent), the current Miami Heat — have been happy at the bottom of the league’s offensive rebounding ranks. League-wide, offensive rebounding rate has been on a prolonged drop. “As a coach, you look at what is most important to winning and construct a game plan around that,” says Jeff Van Gundy. “And offensive rebounding just doesn’t seem to have a correlation with winning big.”
