The 3-2 zone is a defensive strategy used in basketball where three players guard the perimeter and two players protect the paint. This formation aims to limit outside shooting while still providing support against inside scoring. The three perimeter defenders focus on contesting shots and closing out on shooters, while the two inside players are responsible for rebounding and defending against post plays. In a 3-2 zone, communication is crucial among players to ensure proper coverage and to switch assignments as needed. This defense can be effective against teams that rely heavily on outside shooting, as it forces them to take contested shots or drive into a crowded area.
