Offensive efficiency in basketball is a metric used to evaluate a team's or player's performance. It is calculated by dividing the number of points scored by the number of possessions and then multiplying by 100. This formula provides a standard measure for comparing the effectiveness of different teams or players, regardless of their playing style or pace. The resulting offensive efficiency rating (OER) represents the average number of points scored per shot, including missed field goals and free throws. This statistic was developed by Dean Oliver in his book Basketball on Paper, emphasising the importance of considering a player's role in the team when interpreting their offensive efficiency rating.

What You'll Learn
Calculating team offensive efficiency
Offensive efficiency in basketball is a metric that indicates how well a team performs on offense. It is calculated by dividing the total points scored by the team by the number of possessions and then multiplying that figure by 100. This formula can be represented as:
Offensive Efficiency = 100 * (Points Scored / Possessions)
The resulting value represents the number of points a team scores per 100 possessions. For example, if a team scores 80 points in a game and had 60 possessions, their offensive efficiency would be:
Offensive Efficiency = 100 * (80 points / 60 possessions) = 100 * 1.33 = 133
So, their offensive efficiency for that game is 133, indicating they scored 133 points per 100 possessions.
This metric is useful for comparing the offensive performance of different teams, regardless of their playing style or pace. It provides a standardised way to evaluate offensive effectiveness, allowing for more informed strategic decisions and player evaluations.
Additionally, offensive efficiency can also be calculated for individual players, known as the Offensive Efficiency Rating (OER) or Offensive Rating. This metric was developed by Dean Oliver in his book "Basketball on Paper" and represents the points produced by a player per 100 individual possessions. It takes into account factors such as scoring possessions, missed field goal and free throw possessions, and turnovers.

Calculating individual offensive efficiency
Offensive efficiency in basketball is a measure of the number of points scored per 100 possessions. This can be calculated for individual players as well as teams. The formula for individual offensive efficiency, or Offensive Rating (ORtg), is the number of points produced by a player per 100 individual possessions.
To calculate this, we first need to determine the number of total possessions. This can be broken down into four components: scoring possessions, missed field goal (FG) possessions, missed free throw (FT) possessions, and turnovers. Scoring possessions are the most complex component to calculate, and they are made up of field goals, assists, and free throws.
Once we have the total number of possessions, we can calculate the number of points produced by the player. This includes all points scored, including missed field goals and free throws.
It's important to note that, as Dean Oliver points out, offensive ratings should not be viewed in isolation. He introduces the concept of "Skill Curves", which considers a player's ORtg in conjunction with their Usage Rate, or the size of their role in the team's offense. A player with a larger role may find it more difficult to maintain a high ORtg, while a player with a smaller role may be more efficient. Therefore, when comparing players' ORtg, it is most meaningful to compare players with similar roles in their teams.

The impact of pace on offensive efficiency
Pace is a critical element in basketball, especially in the NBA, and refers to the speed of play and control over that speed. It is measured in seconds per possession and allows for a consistent comparison of teams across different eras. A faster pace of play can be used to gain a competitive advantage and put pressure on the defense, resulting in transition points.
A high-tempo offense, when combined with proper spacing, can create advantageous match-ups and change the attack capabilities of a team. For example, Steve Kerr's 2014-15 Golden State Warriors used the small ball formation to create more space, and the Phoenix Suns of the mid-2000s employed the "seven seconds or less" offense, showcasing the impact of pace and space on offensive success.
However, an aggressive approach to pace and space can compromise player safety and lead to turnovers and bad shot choices if the players are not disciplined and precise in their movements and communication. A team may also adopt a slower tempo strategically to save energy or disrupt the flow of faster-playing opponents.
While pace can influence the number of shots attempted and the number of points scored per game, there is only a weak link between shooting efficiency and pace. This suggests that quick play does not necessarily impact shooting percentages, and there is no clear correlation between a faster pace of play and a higher likelihood of winning.
In summary, while pace is a critical element in basketball, the impact on offensive efficiency is complex and dependent on various factors such as spacing, player discipline, and strategic tempo fluctuations.

The difference between offensive rating and floor percentage
Offensive Rating and Floor Percentage are two metrics used to evaluate the performance of basketball players and teams. While both metrics are related to offensive efficiency, they capture different aspects of a player's or team's offensive production.
Offensive Rating, also known as Offensive Efficiency, measures the performance of an individual player or a team's offense. It quantifies the efficiency of the offense by calculating the number of points produced per 100 possessions. The formula for Offensive Rating takes into account various factors, including scoring possessions, missed field goal possessions, missed free throw possessions, and turnovers. This metric provides a repeatable method for comparing and understanding how an offense performs and can be applied to specific players, lineups, or situations within a team.
On the other hand, Floor Percentage, as defined by Dean Oliver, answers the question, "What percentage of the time that a player wants to score does he actually score?" It focuses on the success rate of a player's scoring attempts. Floor Percentage considers the number of times a player attempts to score and the number of times they are successful in doing so.
The key difference between Offensive Rating and Floor Percentage lies in the aspects of offensive performance they evaluate. Offensive Rating calculates the average number of points produced per scoring possession, taking into account all factors that contribute to scoring, such as field goals, free throws, and turnovers. It provides a comprehensive view of a player's or team's offensive efficiency. In contrast, Floor Percentage specifically addresses the success rate of a player's scoring attempts, without considering the various ways in which points can be accumulated or lost.
For example, consider two players: Player A has a high floor percentage, indicating that they consistently score when they attempt to. However, if Player A rarely attempts to score and accumulates points primarily through free throws, their offensive rating may be lower compared to a player who frequently attempts field goals and scores at a lower rate. Player B may have a lower floor percentage but a higher offensive rating if they excel at drawing fouls and converting free throws.
In summary, Offensive Rating and Floor Percentage are both important metrics in basketball analytics. Offensive Rating provides a comprehensive view of offensive efficiency by calculating points produced per possession, while Floor Percentage focuses specifically on the success rate of a player's scoring attempts. By understanding the difference between these metrics, coaches, analysts, and fans can gain valuable insights into the offensive performance of players and teams.

The role of defensive efficiency in offensive efficiency
Offensive efficiency in basketball is a metric that calculates the number of points scored per 100 possessions. It is a tempo-free statistic, providing an unbiased view of a team's performance, regardless of their playing style. This metric is calculated using the formula: Offensive Efficiency = 100 * (Points Scored / Possessions).
The defensive efficiency rating (DER) is a complementary concept, reflecting the number of points conceded or given up per possession. When considering offensive efficiency, the defensive strategies employed by the opposing team are inherently factored in. This is because offensive efficiency is calculated relative to the opportunities or possessions available, which are inherently influenced by the defensive tactics deployed.
For instance, a strong defensive strategy may limit the number of possessions or opportunities for the opposing team, thereby reducing their potential to score points and lowering their offensive efficiency. On the other hand, a weak defensive strategy may result in more possessions for the opposing team, increasing their chances of scoring and improving their offensive efficiency.
The interplay between offensive and defensive efficiency is crucial. A team with a high offensive efficiency aims to maximise their scoring opportunities, while a team with a high defensive efficiency seeks to minimise their opponent's scoring chances. Therefore, to fully understand and improve offensive efficiency, it is essential to consider the defensive strategies employed by both teams.
Additionally, individual player roles and contributions cannot be overlooked. Dean Oliver, who developed the offensive and defensive ratings in his book, "Basketball on Paper," emphasised that a player's offensive rating should be judged in conjunction with their usage rate. A player with a larger role on the team may find it more challenging to maintain a high offensive rating, while a smaller role can facilitate higher efficiency. Thus, when evaluating offensive efficiency, it is important to consider the specific roles and contributions of individual players, as their performance can significantly impact the team's overall efficiency.
