Understanding Basketball's 'To' Terminology

what is to in basketball

In basketball, TO refers to the number of points scored immediately after a turnover. It is one of the many statistics used to evaluate a player's or team's performance. Other statistics include EFF (efficiency rating), plus-minus metrics, PIR (Performance Index Rating), and more. These metrics help quantify a player's impact on the game, taking into account various factors beyond just points, rebounds, and assists.

Plus-Minus statistics

However, there are some limitations to plus-minus statistics. Firstly, they are heavily influenced by teammates. For instance, a great player on a poor team might show negative values, while an average player surrounded by good teammates might appear more impactful than they are. Secondly, single-game or small-sample Plus-Minus data can be misleading, as it can be influenced by the quality of the opponent team or specific game situations such as rest days. Finally, while Box Plus/Minus is a good offensive metric, it struggles with defence, as it is difficult to estimate defence accurately from a box score alone.

Despite these limitations, Plus-Minus statistics provide valuable insights into a player's impact on the game, capturing the "invisible" contributions that traditional box scores miss. They are used by modern basketball organisations, with front offices leveraging the data to inform draft decisions and free-agent acquisitions, and coaches using it to optimise lineup combinations and rotation patterns.

Efficiency ratings

Efficiency in basketball is a composite statistic that is used to compare the overall value of players. Efficiency ratings are calculated using a multitude of basic individual statistics, including points, rebounds, assists, steals, blocks, turnovers, and shot attempts. The NBA measures individual efficiency in four ways: Efficiency (EFF), Player Efficiency Rating (PER), Offensive Efficiency Rating (OER), and Defensive Efficiency Rating (DER).

Efficiency (EFF)

The EFF is a quick way to determine a player's efficiency compared to PER. It pertains to the total value of a player to a basketball team and is calculated by adding up all of the production stats (points, rebounds, assists, steals, and blocks), subtracting all missed shots (field goals and free throws) and turnovers, and then dividing by games played. One drawback of EFF is that it is heavily focused on offense rather than defense.

Player Efficiency Rating (PER)

PER is the most popular and mainstream NBA advanced stat. It was created by sportswriter John Hollinger in the late 1900s to measure each NBA player's overall impact on the game. PER is calculated using a detailed formula that rates every player's statistical performance and measures their per-minute performance, while adjusting for pace. PER takes into account positive results, including field goals, free throws, 3-pointers, assists, rebounds, blocks, and steals, and negative results, including missed shots, turnovers, and personal fouls. The formula adds the positive statistics and subtracts the negative ones, and each player’s rank is then adjusted on a per-minute basis. A PER of 15 is considered average across the league, while a PER above 20 is considered great, and anything above 25 is considered elite.

Offensive Efficiency Rating (OER)

OER is calculated using the number of points scored per shot taken, including free throws. Offensive rating is measured by points scored per 100 possessions.

Defensive Efficiency Rating (DER)

DER is a measurement that estimates how many points a given player is expected to allow over 100 possessions. DER is difficult to track for individual players and relies on the defensive quality of teammates.

Performance Index Rating (PIR)

The EuroLeague, its second-tier level of competition, the EuroCup, and several European national domestic leagues use a different formula called the Performance Index Rating (PIR). PIR takes into account points, rebounds, assists, steals, blocks, fouls drawn, missed field goals, missed free throws, turnovers, shots rejected, and fouls committed.

Points per possession

The formula for calculating PPP is given as:

> Pts / (FGAt + 0.44 × FTAt – OREBt + TO)

Here, Pts refers to points, FGAt to field goal attempts, FTAt to free throw attempts, OREBt to offensive rebounds, and TO to turnovers. The 0.44 factor in the formula is used to accurately represent the number of possessions used during free throw attempts. This factor accounts for the fact that players may get one, two, or three free throw attempts, and that a technical foul may not result in the end of a possession.

PPP is related to the concept of conversion rate, which refers to how often a team scores when given the chance. However, PPP takes into account the different scoring options in basketball, such as three-pointers, two-pointers, and free throws.

While PPP is a useful metric, it does have some limitations. For example, it does not factor in the quality of the opposing team, which can distort the statistic. Additionally, PPP does not consider the starting point of a possession, which may be more or less advantageous depending on the game situation.

Blocks and steals

On the other hand, steals occur when a defensive player legally takes possession of the ball from an offensive player. This can be done by deflecting or intercepting passes, pokeing the ball away from the dribbler, or even by stripping the ball from an opponent's hands. Steals are often a result of quick reflexes and anticipation, and they can quickly turn defense into offense for a team.

Both blocks and steals are recorded as statistics in basketball and are used to evaluate a player's defensive performance. They are considered to be some of the most impressive and impactful defensive plays in the game. While blocks tend to be associated with taller players who can cover more area near the basket, steals can be achieved by players of any position, although smaller and quicker guards tend to accumulate the most steals.

Some of the most notable players known for their blocking abilities include Hakeem Olajuwon, who is ranked in the top 10 all-time for blocks, and Walt Frazier, who was renowned for his overall defensive mastery. As for steals, legendary players like Allen Iverson, Michael Jordan, Chris Paul, and John Stockton have consistently led the league in this category.

In summary, blocks and steals are crucial defensive aspects of basketball that can significantly influence the outcome of a game. They require a combination of athleticism, timing, and strategic thinking. By mastering these skills, players can disrupt their opponents' offense, create scoring opportunities for their team, and ultimately improve their chances of winning.

Rebounds

In basketball, a rebound is a statistic awarded to a player who retrieves the ball after a missed field goal or free throw. It is a pivotal skill that significantly influences the flow and outcome of the game. The primary purposes of rebounding include: providing a team with a fresh shot clock and another chance to score, and preventing the opposing team from getting second-chance opportunities.

There are two main categories of rebounds: offensive rebounds and defensive rebounds. Offensive rebounds occur when a player on the offensive team retrieves the ball after their team's missed shot. This provides the offensive team with another opportunity to score. Defensive rebounds occur when a player on the defensive team retrieves the ball after the opposing team's missed shot. This prevents the opposing team from getting second-chance opportunities to score and allows the defensive team to transition to offense.

Great rebounders tend to be tall and strong, as height and strength can be advantageous in positioning for and retrieving rebounds. However, players of any height can be successful rebounders with the right technique. It is important to be able to predict where the ball might go after a missed shot and to position oneself accordingly. This includes using the box-out technique, which involves positioning the body to keep opponents away from the ball and make it easier to retrieve the rebound. Jumping to grab the ball at its highest point can also increase the chances of a successful rebound.

Rebounding is a crucial aspect of basketball that can significantly impact the outcome of a game. It requires a combination of skills, including strength, agility, and endurance, as well as a keen sense of timing and positioning. By understanding the techniques and strategies involved in rebounding, players can improve their overall performance and contribute to their team's success.

Frequently asked questions

TO stands for Turnover, which is the number of points scored immediately after a turnover.

TO is determined by the user first selecting a turnover. Then, if the next statistical event is a made basket of any type by the opposing team, turnover points are recorded.

The formula for a player's efficiency in basketball is:

(Points + Rebounds + Assists + Steals + Blocks) − ((Field Goals Attempted − Field Goals Made) + (Free Throws Attempted − Free Throws Made) + Turnovers)
