The sideline is your fifth defender on a break

Angles beat bodies when you are outnumbered, and the touchline does defensive work that no rotation can replicate.

Two on one. The textbook says the defender splits the difference, fakes at the ball, recovers to the pass. The textbook is fine and it is also solving the wrong problem, because it treats the floor as an open field when the floor has an edge, and the edge is on your side.

A break is dangerous in the middle. The moment the ball reaches the centre of the floor, every passing angle is available and a defender has to honour both sides of his own body. Push the same ball to a lane outside the elbow extended and half the offence disappears. The far side pass now travels forty feet across a defender's field of vision, which is slow enough to be read, and the driver's finishing angle at the rim narrows to the awkward side of the backboard.

So the first defender back should not think of himself as guarding a man. He should think of himself as building a wall on one side and inviting traffic onto the other. Angle before position. He wants his shoulders turned so the easy route is toward the touchline, and he wants to arrive early enough that the ball handler chooses that route without noticing he has been steered.

This is where I part company with a lot of coaching. The instruction most players receive is to stop the ball. Stopping the ball at the top of the key in the middle of the floor is often worse than never touching it, because the offence gets to pick up, survey, and swing to the trailer with everyone still scrambling. I would rather concede two contested steps down the sideline than force a pickup in the centre.

The second defender back then has an easy job, and easy jobs are what a good scheme manufactures. He does not have to guess. He knows the ball is going one way, so he takes away the first pass on the near side and lets the long skip travel, because a long skip pass in transition is a coin flip and a deflection candidate at the same time.

None of this needs athletes. It needs agreement about which way the funnel points, and every team I have watched blow a two on one had two defenders funnelling in opposite directions.

The court is ninety four by fifty. Use the fifty.
