The motion offense explained

A motion offense is a style of attack built on principles and constant movement rather than fixed, scripted plays. Instead of running a set sequence every time, players are given rules to follow, such as passing and moving, screening for one another, cutting to the basket and keeping the floor spaced. Within those guidelines they read the defence and react, so the offence is never quite the same twice and flows continuously.

The defining feature is that no one stands still. After a player passes the ball, he does not watch it; he cuts, sets a screen or relocates to keep the defence busy. Off-ball players are always moving to create and use space. This continuous motion forces defenders to keep tracking their assignments and communicating, and any lapse in concentration can immediately be punished by a cutter slipping free toward the basket.

Because it is based on reads rather than a fixed script, a motion offense rewards intelligent, unselfish players who understand spacing and timing. A cutter goes when the defender turns his head; a screen is set when it will free a shooter; the ball moves to wherever the defence is weakest. This shared decision-making makes the offence adaptable, able to attack whatever a defence gives rather than forcing a predetermined action.

A motion offense is difficult to guard precisely because it is unpredictable. A defence cannot simply scout and shut down a handful of set plays, because the offence is generated on the fly from principles. The constant movement, screening and cutting stretch a defence and expose any breakdown in communication. Well-drilled teams can run motion for a full possession until the defence finally cracks and gives up a good, open shot.
