What it is
- Every denial is a backdoor; train players to read denial and backdoor immediately.
- Any time you pass the ball, you must immediately cut — either to the basket (give-and-go) or away from the ball.
- The cut is hard to stop because the guard is moving at full speed using the screen.
Why it matters
- 5-Man Motion Offense (sometimes called "open post motion" or "rules-based motion") is the foundational framework from which most modern offenses derive their principles.
- Rather than running set plays, the offense operates on a set of rules that every player must follow depending on what happens with the ball.
- The origination is often credited to coaches like Henry Iba and Bob Knight, who ran disciplined, rules-based systems.
- The genius of motion offense is that it is positionless — all five players operate by the same rules, making it adaptable to any roster.
How it works
- Rule 4: Post Rule (Optional in Some Systems) - When the ball is on the wing and a post player is present, the post player sets a screen for the opposite wing or cuts to the ball-side block. - Prevents post players from standing and waiting.
- Any time you pass the ball, you must immediately cut — either to the basket (give-and-go) or away from the ball.
- You may NOT stand where you passed from.
- This rule forces constant movement and prevents the defense from settling.
- After passing and cutting to the basket without receiving the ball back, the cutter continues through and sets a screen for the player farthest from the ball (away from the action).
