Basketball offenses explained: the main systems

A basketball offense is a plan for how five players use the floor to get a good shot. It can be a set of rules, a repeating pattern, or a list of called plays. Most real offenses are a mix.

This page covers the systems you will hear about most. For each, you get what it is, what it asks of players, and where to read more.

Rules, patterns and plays

Before the systems, the three ways an offense is built.

• Rules. Players follow principles, such as “pass and cut” or “screen away”. Nothing is called. Motion offense works this way.
• Patterns. A fixed series of cuts and screens that repeats. Flex and the shuffle are examples. See our note on continuities versus quick hitters.
• Plays. A single set designed for one shot, called from the sideline. Many out-of-bounds plays and late-game plays work like this.

Most coaches combine them: a base offense for most possessions, and a few plays for special moments.

Motion offense

A motion offense is a rules-based system with no fixed sets. Players pass, cut, screen and fill open spots by principle. It is hard to scout, because it has no fixed script.

• Needs: players who read the floor and a coach who teaches the rules.
• Strength: it adapts to man and zone.
• Risk: without discipline it becomes five players standing around.

We compare it to set plays in motion offense versus set plays.

5-out offense

Five players stay on the perimeter, so the lane is open. Players pass, cut to the rim, and fill the spot behind the ball.

• Needs: five players who can pass, catch and move.
• Strength: it teaches spacing, and it suits youth teams.
• Risk: with no inside player, rebounding needs a plan.

A close cousin is 4-out, 1-in, which keeps one big near the basket.

1-4 high

The ball handler at the top and the other four in a line at the free-throw line extended: two wings and two posts at the elbows. It is a common alignment for set plays and for attacking a defense that overplays.

• Needs: a passer at the high post and cutters who can beat a denial.
• Strength: backdoor cuts are open when defenders overplay.
• Risk: guards must be able to make the passes.

Horns

Two players at the elbows, two on the wings or in the corners, and a ball handler up top. It is a quick-hitter set with many options coming out of it.

• Needs: two bigs who can screen and pass, and a guard who can read.
• Strength: one alignment gives you a ball screen, a pin-down and a flare.
• Read more: Horns offense.

Flex

Flex is a continuity built on a baseline screen and a down screen that repeat. The cut that follows the baseline screen is the flex cut.

• Needs: screeners who set screens on time and cutters who cut tight.
• Strength: it is easy to run against man defense, and it puts screens on every possession.
• Risk: it is predictable if you never vary it, and it is hard for very young players.

Princeton

The Princeton offense is named for the Princeton University teams that made it famous. It uses backdoor cuts, passing from the high post and patient reads. The chin series, a back screen followed by a flare, is a set closely associated with it.

• Needs: big players who pass well and guards who cut hard.
• Strength: it punishes defenders who overplay.
• Risk: it needs time to teach, and players must trust the reads.

Dribble drive

A dribble drive offense uses spacing around a driver. One player attacks the rim while teammates spread and move to open spots. It is often run from a 4-out or 5-out look.

• Needs: guards who can beat a defender and shooters who are ready.
• Strength: a drive pulls help defenders, and the kick-out finds the shooter.
• Risk: drives that end in tough shots. Teach the kick-out early.

Set plays and continuities

Set plays and continuities do different jobs.

	Continuity	Set play (quick hitter)
Length	Repeats until a shot	Runs once
Best for	Normal possessions	Special moments
Teaching load	Higher, one big idea	Lower, one play at a time
Examples	Flex, shuffle	Horns sets, out-of-bounds plays

Use set plays after a timeout, out of bounds, and at the end of a game. Use your base offense the rest of the time. For late-game sets, see our ATO plays guide.

Offense against man and against zone

Most offenses were built against man-to-man defense. Against a zone, the same ideas bend.

• Motion and 5-out transfer well. Keep the ball moving, and cut to the gaps instead of to a defender.
• Flex and Princeton lose some force against a zone, because screens and backdoor cuts have fewer defenders to beat. Use them against a team that switches between man and zone.
• Horns and 1-4 high give you a high-post catch, which is the first thing a zone concedes.

If you meet a zone often, keep one extra set for it and use the rest of the system as it is.

What each system asks of players

Match the system to the skills, not the other way round.

System	Passing	Shooting	Screening	Teaching time
Motion	High	Medium	Medium	Long
5-out	Medium	High	Low	Short
Flex	Medium	Medium	High	Medium
Princeton	High	Medium	Medium	Long
Dribble drive	Medium	High	Low	Medium

The ratings are our judgment, not a measurement. Your team may differ.

How offenses change with age

The right system depends on how old your players are.

• U10 and U12. Spacing, passing and cutting. A 5-out pass-and-cut offense is plenty, with one out-of-bounds play.
• U14 and middle school. Add one ball screen and one pin-down. Keep the base offense the same.
• High school. Add a continuity or a set structure, such as horns, and a package for the end of games.
• Older teams. Read-and-react systems become possible, because players have seen the same situations many times.

Adding a system is not the same as improving. A team that runs one offense well will beat a team that runs four badly.

How to choose

Start from your players, not from the diagram.

1. Count your skills. Passers, shooters, drivers, screeners.
2. Pick a base offense that uses what you have. Most youth teams should start with 5-out.
3. Add three or four plays for out of bounds and the end of games.
4. Keep it for the season. Changing the system in January means starting over.

For younger teams, see basketball plays for U12 and U14. For attacking a zone, see how to beat a 2-3 zone.

One last rule

Whatever you pick, teach the same three habits first: space the floor, move after you pass, and read the defender in front of you. Every system on this page is built on them. A team without those habits will fail in any of them, and a team with them can learn any of them quickly.

Drawing it up

An offense lives in your players’ heads. A diagram helps to put it there. SlongeHoops lets you draw a play, watch it run and share the link, and the built-in plays above are examples you can open and change. It does not choose an offense for you.
