Flex Offense Explained: How the Flex Offense Works in Basketball

The flex offense is a continuity offense in the sport of basketball. The flex offense uses a flex cut to give the shooter room for a layup or a jump shot from the high post, with the assistance of screening and passing. One of the simplest forms of continuity offense, it has the combined benefit of being great for beginners and highly effective if executed properly. Basketball players from high school to college to the professionals of the NBA use the flex motion offense.

The flex offense is an offensive strategy that requires even spacing, making it suitable for beginners and youth basketball. It also prevents players from being overly reliant on their dribbling, encourages passing, and requires awareness of the whole team’s positions. The strategy uses all team members; once the point guard advances the ball and makes the initial pass, all positions are changeable. This helps teams with their cohesion and requires solid fundamentals from all players.

The flex offense, originally known as the “cha cha,” is a variation of the shuffle offense. The strategy was developed in 1967 to bring UCLA’s center, future NBA star Kareem Abdul-Jabbar, away from the ball. It eventually became very popular throughout the league and beyond. Coach Gary Williams had great success with the flex offense, leading the University of Maryland to NCAA victory in 2002 with the strategy.

All variations of the flex offense center on the basic flex continuity. The formation and steps are as follows:

1. 1. Formation: The basic formation of the flex offense involves two players at the top of the key, one on each wing, and one on the block of the low post area (which side of the key depends on where the ball is). The idea is that each of these positions is filled at any moment of the offense, even though any player can occupy any of the positions, depending on the offense’s progress and how the defense is responding.
2. 2. Passing: The continuity starts with one of the players at the top of the key passing the ball to the other.
3. 3. Flex action: The passing triggers the flex cut from the weakside wing player, who cuts into the paint—either on the baseline side or the block side—with the post player making a flex screen. Then, the original passer sets a down screen for the original screener, who replaces them near the top of the key.
4. 4. Repetition: This process repeats, but with the sides reversed. Players can cycle through repeatedly, adding ball reversals, gradually causing the defense to break down.
5. 5. Variations: From here, there are many variations players can perform—back screens from a sideline out of bounds, backdoor cuts down to the low post, ball screen sets—all of which can help the offense pressure and confuse the defense, leading to scoring opportunities.

The flex offense is primarily a man-to-man offense, although basketball coaches can adjust it to work against zone defense patterns.

The flex offense has the benefit of being a great way to teach basketball. Teammates have to learn to read each other’s movements, pay attention to their position, effectively communicate, and respond to sudden changes. Follow these tips to teach your team the strategy:

1. 1. Start the flex offense slowly. The flex offense does not need to be quick to work effectively. Have the players go through the basic continuity until they have it down; then, you can incorporate it into the gameplay.
2. 2. Work on variations. As the team learns the flex offense, coaches can set plays that rely on variations of the basic pattern. You can employ double screens, attempts to draw fouls and make free throws, and switch the play up with other offenses to avoid predictability.
3. 3. Combine basketball drills. You can have players practice a simplified version of the flex offense to work on other moves and tactics. Shooting drills can incorporate the screening and cutting moves of the flex offense.

Despite some variations, the flex offense is a standard in many basketball playbooks and is widely recognizable. The defensive team may defend against the flex offense by stopping the initial pass. When the first guard-to-guard pass occurs, it sets the whole offense in motion. If this pass can be prevented, such as with high pressure in a man-to-man defense, the flex continuity cannot start, effectively stalling the offense.

The defensive team can also switch the screens, allowing the guards to stay out near the wings and the post player to stay close to the basket. This prevents the pattern of the flex offense from being truly effective.
