Backboard Bank Shots: The Science Behind The Swish

what percentage of basketball shots are made using the backboard

The bank shot is a type of shot in basketball where the ball hits the backboard before going into the net. It is considered by some to be a less popular shot, as players are typically taught to aim for the hoop and not the backboard. However, research by engineers at North Carolina State University has shown that a bank shot can be up to 20% more effective than a direct shot when shooting from certain angles and distances. The study, which simulated one million shots with a computer, found that the optimal aim points for a bank shot form a V shape near the top centre of the backboard. Despite the potential advantages of the bank shot, some basketball players and coaches still consider it to be less desirable or effective than other types of shots.

Bank shots are 20% more effective than direct shots from certain angles and distances

Research by engineers at North Carolina State University found that bank shots can be more effective when shooting at many angles up to a distance of about 12 feet from the basket. The study simulated one million shots with a computer, and the results showed that the bank shot can be more successful than a direct swish.

The optimal aim points for bank shots make a "V" shape near the top center of the backboard's "square." This "square" is actually a rectangle that measures 24 inches by 18 inches and surrounds the rim. When shooting from the free-throw lane, the aim points are lower on the backboard and closer to the rim. From outside the free-throw lane, the aim points are higher on the backboard and further from the rim.

Bank shots are also more effective from certain areas of the court. For example, areas on the wing between the free-throw area and the outermost three-point line contain pockets where a bank shot is much more likely to go in than a direct shot.

While bank shots can be more effective from certain angles and distances, they are not always the best option. Straight-on shots from further than 12 feet are not as well-suited for bank shots. Additionally, the traditional way of shooting is to aim for the rim, and it can be challenging to retrain players to use bank shots.

The optimal target point for bank shots makes a 'V' shape near the top centre of the backboard

The game of basketball is a complex interplay of physics and human skill. Researchers have been intrigued by the question of whether it is better to shoot the ball straight at the rim or aim for the backboard. A study by North Carolina State University researchers, led by Dr. Larry Silverberg, set out to answer this question. The study simulated one million shots with a computer to determine the optimal target points on the backboard for bank shots in men's basketball.

The study found that the optimal aim points for bank shots form a "V" shape near the top centre of the backboard. This "V" shape is located on the 24-inch by 18-inch rectangle that surrounds the rim. The specific aim point depends on the player's location on the court. When shooting from away from the free-throw lane, the optimal aim points are higher on the backboard and further from the rim. Conversely, when shooting from closer to the free-throw lane, the aim points are lower on the backboard and closer to the rim.

To visualise this concept, imagine a vertical line located 3.326 or 3.327 inches behind the backboard. The optimal spot to bank the basketball is where this vertical line crosses the "V" shape on the backboard. This crossing point represents a high-percentage bank shot, providing players with an intuitive target to improve their shooting accuracy.

The study also revealed that bank shots can be up to 20% more effective than direct shots when shooting from certain areas of the court. These areas are known as ""wing" areas, located between the three-point line and the free-throw lane. However, straight-on shots from beyond 12 feet are less suited for bank shots.

The findings of this study have important implications for basketball coaching and player development. By understanding the optimal target points for bank shots, coaches can teach players to visualise the "V" shape and vertical line, improving their accuracy and scoring ability.

Tim Duncan is considered the best at using the backboard for shots

While there is no clear data on what percentage of basketball shots are made using the backboard, researchers at North Carolina State found that there are large, identifiable areas on the court where a bank shot can be up to 20% more successful than attempting a direct swish.

Tim Duncan is considered by many to be the best at using the backboard for shots. Duncan played for the San Antonio Spurs for nearly two decades, and his bank shot is considered one of the best "filthy" signature moves in NBA history. One fan comments that Duncan "CONSISTENTLY uses [the backboard] on his shots", and another states that "TD just happens to be the best at it".

Duncan's bank shot was described as "mundane yet successful", and it was noted that he could seemingly get to it whenever he wanted. His range extended well beyond the paint, and it felt almost automatic. Duncan's ability to use the backboard so effectively may be due to his ability to catch the ball in one of the "sweetest spots" to hit the backboard. This allowed him to create high-percentage shots, as banking a shot is often easier than a straight-up three-pointer or regular jump shot.

In addition to his consistent use of the backboard, Duncan was also known for his self-lobs or alley-oops off the backboard. While this move was considered taboo in 1998, Duncan popularized it and made it his signature.

It's harder to use the backboard for shots from the perimeter

While using the backboard can increase the chances of scoring a basket by up to 20%, it is harder to use the backboard for shots from the perimeter. This is because, when shooting from further out, there is a higher chance of the ball bouncing off the backboard and missing the rim. The velocity of the shot from the perimeter increases the likelihood of this happening.

Additionally, most players are taught to aim for the rim, and it can be challenging to deviate from this instinctual approach. The fundamental skills of basketball, such as shooting at the hoop, are often deeply ingrained in players, and it can be difficult to unlearn these habits. This is further influenced by the perception that using the backboard is less "cool" or impressive than direct shots.

The effectiveness of using the backboard also depends on the angle of the shot. Perimeter players may not always have the optimal angle to utilize the backboard effectively, and therefore, they might opt for a more conventional shot.

Furthermore, the backboard's surface area decreases as the shooting distance from the basket increases, making it even more challenging to execute successful bank shots from the perimeter.

Despite these challenges, some players, such as Ben Gordon and Dwyane Wade, have incorporated the use of the backboard into their shooting repertoire, showcasing its potential as a valuable skill to develop for players looking to expand their offensive capabilities.

Bank shots are often seen as less cool than direct shots

Another factor contributing to the perception of bank shots as less cool is the instinctive nature of shooting directly at the rim. When we see the rim, we want to shoot the ball at it, and shooting bank shots goes against this human instinct. It requires players to train their eyes to launch the ball at an arbitrary point away from the rim, which can feel unnatural and uncomfortable.

Additionally, the use of bank shots may be seen as a sign of weakness. In a game, players want to showcase their skills and abilities, and using the backboard can be seen as a crutch or a way to compensate for a lack of shooting ability. This perception may be especially prevalent among younger players, who are more likely to be influenced by the desire to perform impressive, attention-grabbing moves.

Furthermore, the use of bank shots may be seen as a break from the traditional or "fundamental" way of playing basketball. Most people learn to shoot by aiming at the hoop, not the backboard, and deviating from this familiar technique can be seen as unconventional or even wrong. This is reflected in the comment of a youth basketball player who refused to use the backboard, stating that "using the backboard is for faggots".

Despite the perception that bank shots are less cool, research suggests that they can be more effective than direct shots, offering up to a 20% higher success rate from certain areas of the court. This advantage is particularly notable in the "wing" areas between the three-point line and the free-throw lane. However, the social and psychological factors mentioned above may contribute to the continued perception of bank shots as less desirable or impressive than direct shots.
