What it is
- Ball-screen defender and big defender communicate and swap assignments
How it works
- Mechanics: Ball-screen defender and big defender communicate and swap assignments
- Mechanics: POA takes the roller as primary defender
- Mechanics: Big takes the handler
- Mechanics: Both defenders "switch" at point of screen
- Mechanics: Weakside help adjusts (if big is now on handler, paint is exposed)
Reads and counters
- On-ball defender reads the screen angle and calls switch early so both defenders exchange cleanly without ball-handler splitting the seam.
- If the switch leaves a small on the roller, that smaller defender reads the seal and fronts or three-quarters before the post catch.
- Screener's defender reads a slip or ghost: if the screener bolts early, stay home and the on-ball defender never has to switch.
- Read the offense's intent to attack before help sets; the switching guard must body the bigger handler and force a contested first dribble.
- Weakside defenders read which switch created the mismatch and pre-rotate low-man help toward the exposed paint.
Teaching cues
- Switch it, hands up
- Body the bigger man
- Front the post, no seal
- Stay home on the ghost
- Scram, switch out the mismatch

Reading Switch Coverage
A switch occurs when the screening defender and the ball handler's original defender exchange assignments: the screening defender guards the ball handler, and the ball handler's original defender guards the roller.
