STEVE KERR'S SYSTEM
Split Motion
The four players without the ball are the offense — cut, screen, relocate, and turn one defensive blink into a layup.
“Joy, competitiveness, mindfulness, compassion — that's the whole program.”
Kerr's Warriors weaponized the moments defenses use to rest. Pass and cut — the vacuum fills itself. A defender ducks under a screen — that's not a failed action, that's the shot the offense wanted. A switch happens — now there's a mismatch on both ends of it, and the offense chooses which one to eat. A defender turns his head to watch the ball — his man is already gone backdoor. Nothing in the system requires a superstar; it requires four players who keep moving after the pass and one rule the Warriors never break: the ball doesn't stick. Half a second of hesitation kills the advantage.
- Off-ball movement wins: cut, relocate, space. The defense can only watch one thing.
- Joy in the game — playing loose produces better decisions than playing tight.
- Drive and kick reads: angles and timing. The drive creates, the kick converts.
- The ball never sticks. Half a second of hesitation kills the advantage.
THE SHAPES IT HUNTS
Five-Out Cut (The Vacuum)
In five-out, every pass from the top pulls a cork: the passer cuts through the empty lane and the whole floor rotates one spot.
The Turned Head (Backdoor Window)
The denying defender's head is turned to find the ball — the lane behind him just opened for the backdoor cut.
Ducked-Under Screen
The on-ball defender slides under the screen instead of chasing over it — he's conceding the pull-up behind it.
The Switch Mismatch
The switch left their big guarding the ball and their small guarding yours — two mismatches on the floor at once.
RUN IT AT THE PARK
The pickup version is two habits. First: never stand still after passing — cut to the rim, then fill out to an open spot. You'll get two backdoor layups a game just from defenders who ball-watch. Second: when your defender ducks under anything — a screen, a handoff, even a teammate standing still — stop behind it and shoot; that space is a gift with your name on it. You don't need to run splits like Golden State. You need to make your defender pay attention to you for the whole possession, because at the park, nobody does.
HOW TO BEAT IT
Movement offense runs on trust between cutter and passer, so attack the connection: switch every screen and cut, and the motion produces no separation — just a new defender in the same spot. Stay home on shooters and refuse to help two passes away; the backdoor game needs a ball-watcher to exist. And make the cutters run through contact — a forearm at the start of every cut slows the whole machine until it's five players standing around one dribbler.
