Offensive rebounding rates across the league have been sliding for the better part of a decade, and the standard explanation is that teams are protecting against transition defense. Send too many to the glass, the thinking goes, and you’re sprinting back to defend a four-on-three. It’s a reasonable concern. It’s also become a crutch that teams use to avoid examining something more uncomfortable: they’ve built rosters that are structurally allergic to interior contact.
The stretch big proliferation didn’t just change where bigs operate on offense - it changed what they’re willing to do. A center who spaces to the corner on a drive doesn’t crash. He’s not supposed to. His value is in the geometry of his positioning, not in fighting for position on the glass. That trade-off made sense when three-point shooting was undervalued. Now that every team has internalized the math, the glass has become genuinely under-contested in ways that don’t show up cleanly in box scores.
What’s less discussed is that this is a coaching philosophy problem as much as anything. Teams like the Oklahoma City Thunder under Mark Daigneault have shown you can be analytically sophisticated and prioritize offensive rebounding as a systemic habit - not just an opportunistic one. OKC’s 2023-24 season ranked near the top of the league in offensive rebound rate, and they weren’t doing it with throwback bruisers. They were doing it with wings who had been coached to read release angles and commit to the chase. That’s a decision, not a roster accident.

The Selective Crashing Myth
Most teams now run “selected” crashing schemes - only certain players attack the glass in certain actions, based on pre-scouted tendencies. In theory, this is efficient. In practice, it produces half-hearted efforts from players who have mentally categorized themselves as non-crashers before the shot even leaves the shooter’s hands. The glass doesn’t reward ambivalence.
The irony is that second-chance points remain one of the more reliable ways to generate high-value offense late in shot clocks, exactly the situations where half-court sets stall. Teams that have quietly retained a genuine crashing mentality - not just a token big sent to the rim - tend to be harder to close out against in clutch possessions. Whether that’s correlation or causation probably depends on the roster. But at some point, the league-wide retreat from the offensive glass starts to look less like strategy and more like collective forgetting.
