Down Screen
Screen the player coming up from the block — the foundation action of off-ball offense.
The down screen is the most-run off-ball action in basketball. The basic mechanic: a higher player (typically at the elbow) sets a screen for a lower player (on the block) coming up to the wing. The cutter catches at the three-point line; the screener reads the defense and reacts.
Most named off-ball plays in basketball are variations of the down screen. Quick is a wide down screen. Zipper is a vertical down screen up the lane. Iverson cut layers two down screens together. Once players learn the down screen and its reads (cutter curl/flare/pop/back-cut, screener roll/pop/slip), they can play within any named play that uses the action.
Defensively, down screens are coverage challenges because the defender has to make a fight-over-or-under decision in real time. Modern defenses often switch down screens to avoid the fight, but switching creates a mismatch when the screener is a big and the cutter is a guard. The offense reads the response and counters accordingly.
Key principles
- Screener positions near the elbow or high-post
- Cutter starts on the block and runs up off the screen toward the wing
- Screener reads coverage: roll if defender chases over, pop if defender goes under, slip if defender hedges
- Foundation action for dozens of named plays (Quick, Loop, Iverson, Zipper, etc.)
