Nobody crashes the offensive glass anymore and it shows

Transition defence became the priority and second chances quietly became somebody else's problem.

There is a possession I keep rewinding. Shot goes up from the left wing, it is a decent look, and before the ball has even reached its highest point four players are already turning and running the other way. One man is left near the rim, and he is not really contesting, he is just standing there with his arms half up in case it drops in his lap. The rebound goes to the defence untouched. Nobody did anything wrong. That is the part that bothers me.

Offensive rebounding got coached out of the game for a defensible reason. Give up a second chance and you cost yourself roughly a point. Give up a transition bucket the other way and you cost more than that, because the numbers on early offence are brutal and everybody has seen them. So the instruction became simple. Get back. Protect the floor. Live with one shot.

What got lost in that trade is that it was never a binary. Sending four is reckless. Sending nobody is a different kind of reckless, and it is harder to see because the cost shows up as an absence. There is no highlight for a rebound that was available and nobody went for it.

The teams doing this well have stopped treating it as a team rule and started treating it as a read. Who took the shot, from where, and which way is the ball likely to come off. A long two from the wing comes off long and to the opposite side far more often than not. If your big is already on that side, he is not gambling by going, he is just standing where the ball is going. Meanwhile the shooter, who is nowhere near the rim anyway, is the one who sprints back.

I would also argue the deterrent value is real and never appears in any box score. A defence that knows nobody is crashing can leak out early. Two bodies on the glass, even unsuccessfully, keeps five defenders honest for another second and a half, and a second and a half is most of a transition advantage.

We went from an era where crashing was mindless to one where staying home is equally mindless. The answer was always somewhere in between, and it requires trusting players to decide in the moment rather than obey a rule.
