Every team uses a system on offense and defense, even if it is simple. Knowing the main ones helps players understand their role and helps fans read what is happening on the court.

Offensive systems
- Motion offense: players follow principles (pass, cut, screen away, keep spacing) rather than set plays. Flexible and hard to scout.
- Pick-and-roll: a screener sets a pick for the ball-handler and then rolls to the basket or pops out. The most common action in modern basketball.
- Princeton offense: constant movement, backdoor cuts and passing from the high post, made famous by Princeton University.
- Triangle offense: a sideline triangle formation with many reading options, used by the Chicago Bulls and Los Angeles Lakers championship teams under Phil Jackson.
- Fast break / transition offense: pushing the ball before the defense sets up.

Defensive systems
- Man-to-man: each player guards one opponent. The most common defense, and the foundation of all others.
- Zone defense: each player guards an area. Common versions are the 2-3, 3-2 and 1-3-1. Zones protect the paint and hide weaker defenders but can leave shooters open.
- Press: full-court or half-court pressure to force turnovers and speed up the opponent.
- Match-up zone and switching defenses: hybrids that combine zone positioning with man-to-man principles.
In the NBA, the defensive three-second rule limits how long a defender can stay in the paint without guarding someone, which shapes how zones are played at that level.
How teams adjust
Coaches adjust during games: switching defenses to disrupt rhythm, attacking a zone with shooters and the high post, slowing the tempo when ahead. The best teams have a main system and a few counters.
