What You'll Learn
Game strategy and probability
Basketball is a strategic game that involves a lot of mathematics. The game can be analysed using complex systems theory, which considers the interactions of the players and their roles within the team. For instance, historically, power forwards and centres would operate under the basket, but now they shoot three-pointers and handle ball distribution.
Coaches play a crucial role in the game's strategy, constantly studying the gameplay and making adjustments to outsmart the opposing team. They also need to ensure they have the right players on the court, with the best combination of skills to work together efficiently and adapt to the opposing team.
There are two main types of defence in basketball: zone defence and man-to-man defence. Zone defence is where each player has a specific area of the court to defend, and it is often used against teams with a strong inside offensive game but a weak outside game. On the other hand, man-to-man defence assigns each player to cover a specific offensive player wherever they go on the court. This type of defence is effective against strong outside shooting teams and can also help with rebounding. Teams may also combine these strategies, such as in a box-and-one defence, where four players play zone and one player plays man-to-man, usually covering the offensive team's best player.
Offensive strategies may include designed plays, with some teams preferring a fast-paced game to take advantage of their speed and athletic players, while others may opt for a slower, more methodical approach, making use of their designed plays and outside shooting. Passing is key to a good offensive strategy, as it can create openings and cause the defence to adjust, leading to better scoring opportunities. One common offensive tactic is the pick-and-roll, where one offensive player obstructs a defender guarding the player with the ball, creating confusion and potentially leaving one of the offensive players open for a shot.
Mathematics is used extensively in basketball, from the geometry of the court and equipment to the calculation of scores and player statistics. The rectangular court, the height of the hoop, the circumference of the hoop, and the measurements of the ball are all examples of geometric shapes and measurements that are relevant to the game. Additionally, mathematical calculations are used to determine the mean, mode, median, and range of scores, as well as the number of players and their positions.

Player performance tracking
One example of player-tracking technology is the KINEXON PERFORM system, which is widely used by NBA teams and top NCAA programs. KINEXON utilizes IMU (Inertial Measurement Unit) and LPS tracking methods. IMU tracking involves attaching inertial sensors to a player's body, while LPS tracking involves installing sensors or beacons around the basketball court. By combining these methods, coaches, analysts, and trainers can gain comprehensive insights into player performance, facilitating better decision-making, training optimization, and strategic planning.
Player tracking technology has been applied to compare the performances of all-star and non-all-star players in the National Basketball Association (NBA). Studies have found that all-star players tend to outperform non-all-star players in specific areas, including defensive rebounds, close touches, close points, pull-up points, and assists. These findings are reflected in the variables obtained from the tracking systems, which help understand court locations and game statistics, enhancing knowledge of basketball game behavior.
Additionally, player tracking technology has been used to analyze visual tracking speed (VTS) and its relationship with reaction time (RT) in NBA players. The study found that VTS is related to a player's ability to process multiple stimuli on the court, resulting in more positive plays and improved performance measures such as assists and steals.
In conclusion, player performance tracking in basketball heavily relies on technological advancements and mathematical models to capture, analyze, and interpret data. By utilizing these tools, coaches, analysts, and trainers can make informed decisions to optimize player development, improve performance, and gain a competitive edge.

Shot selection and efficiency
Mathematics is used extensively in basketball to determine shot selection and efficiency. Shot selection is a key component in determining offensive efficiency. Coaches and players must clearly define their shot selection philosophy, which includes determining what constitutes a “good shot” for each player and the team as a whole. This definition varies depending on factors such as the players' skills, offensive style of play, and desired shots within the team's range.
To improve shot efficiency, coaches can emphasise the importance of selecting high-value shots with high points per shot (PPS) or points per possession (PPP). Restricted area attempts or shots at the rim have the highest PPS, followed by three-pointers. Coaches can use various strategies, such as the iPhone store analogy, to help players understand the shot hierarchy and prioritise high-value shots. Additionally, tracking shot selection during games and practices can help players visualise how their choices affect the game.
The ROB shot concept, which stands for Range, Open, and Balanced, is another tool to improve shot selection. Players are encouraged to seek ROB shots by avoiding heavily contested and off-balance shots, as there is usually enough time to find a more efficient shooting opportunity. Implementing this concept can be as simple as only scoring ROB shots during practice drills and scrimmages.
Advanced analytics, such as Continuous True Shot Charts, also contribute to understanding shot selection efficiency. These charts incorporate missed shots, shooting fouls, and shot-pursuant free-throw scoring to determine the total scoring yield following a shot decision. By using a generalized additive model (GAM), these charts can estimate player and team shot efficiency as a continuous, three-dimensional surface, with colour-coding representing the expected value of true points at different locations on the court.
By combining these mathematical strategies, coaches and players can make more informed decisions about shot selection, ultimately improving their offensive efficiency and increasing their chances of winning the game.

Statistical analysis
Basketball makes use of several mathematical concepts, and statistical analysis is a crucial aspect of the game. Statistical analysis in basketball involves analysing various data points and metrics to gain insights into player and team performance, as well as making strategic decisions.
One of the most basic statistical analyses in basketball is calculating the mean, mode, median, and range of points scored by each player and the team as a whole. This is often presented in what is known as a "box score", which lists all the players and their respective points. Statistical analysis can also be used to calculate and compare more complex metrics such as Player Impact Estimate (PIE), Net rating, Assisted Field Goal, Usage, Pace, and True Shooting percentage. These advanced statistics can be further broken down and analysed through various combinations of operators and periods. For example, the winning percentage, the time spent on the basketball field, and the order of results can be used to filter and rank players and teams.
Rebounding statistics are another important aspect of basketball analytics. Rebounding refers to a player's ability to gain possession of the ball after a missed shot. By calculating the percentage of missed shots that a player rebounds, coaches and analysts can identify players who are skilled at rebounding and encourage the development of this crucial skill. Assists, which occur when a player helps another player make a basket, are also tracked and analysed. Different leagues, such as the NBA and NCAA, have distinct definitions and calculations for assists. Assist percentage provides an estimate of the percentage of teammate field goals assisted by a particular player.

Geometry and spatial awareness
Basketball is a fast-paced, dynamic, and visually demanding sport. Players need to be able to process visual information, make quick decisions, and be spatially aware. This is where geometry and spatial awareness come into play.
Court awareness is crucial in basketball. It refers to a player's ability to understand the dynamic and spatial aspects of the court during a game. Players need to be aware of their position in relation to the ball, teammates, opponents, and the basket. This knowledge helps them make effective plays, such as setting up for a shot, positioning for a rebound, or playing defence.
For example, a player with good court awareness can quickly assess the situation and decide whether to pass, shoot, drive to the basket, or play defence. They can also use their spatial awareness to navigate the court efficiently, avoid defenders, and find open spaces. This is especially important in transition plays, which involve rapid movements and quick passes. By demarcating the court into distinct sections, athletes can better understand their duties and how they fit into the team's broader game plan.
Spatial awareness also comes into play when it comes to passing and receiving. Players with good spatial awareness can locate teammates and receive passes more effectively, even when navigating ever-changing defences. They can also improve their ability to operate in space and focus from long distances for shooting accuracy.
Additionally, players with strong spatial awareness can better judge in-game distances, especially in congested areas with offensive and defensive players. This is where the role of "bigs" comes in. Bigs are foundational elements of team defence, and they need to be able to recognise and process visual information and communicate commands to their team. With proper alignment and convergence, a big can quickly turn with their back to the basket to locate the rim via spatial awareness.
In conclusion, geometry and spatial awareness are crucial in basketball. They allow players to navigate the court effectively, make quick decisions, locate teammates, improve shooting accuracy, and execute plays. By understanding the dynamic and spatial aspects of the court, players can elevate their gameplay and make smarter, more impactful decisions.
