Plus-minus (also known as the plus/minus statistic) is a statistic used in basketball that measures the net point differential between points scored and points allowed while a certain player is on the court. It is a cumulative statistic that takes into account all the actions of a player during a game, including offensive and defensive contributions, and serves as an indicator of a player’s overall impact on the game.
Understanding Plus-Minus
Plus-minus is a statistic used to measure a player’s overall impact on the game. It is calculated by taking the net point differential between points scored and points allowed while a certain player is on the court. For example, if a player is on the court when his team goes on a 10-0 run, that player will receive a plus-10 rating. On the other hand, if the same player is on the court when his team allows a 10-0 run, that player will receive a minus-10 rating.
In addition to taking into account offensive and defensive contributions, plus-minus also takes into account the other players on the court. This is because the offensive and defensive contributions of all the players on the court are intertwined and affect the overall outcome of the game. For example, if a player is on the court when his team goes on a 10-0 run but the other four players on the court are responsible for most of the offensive contributions, that player may still receive a positive plus-minus rating for his contribution to the team’s success.
Calculating A Good Plus-Minus
When it comes to calculating a “good” plus-minus, there is no definitive answer since the statistic takes into account a wide range of factors. However, a good plus-minus typically falls somewhere between 0 and +10.
A player with a plus-minus of 0 is considered to be an average player who has neither helped nor hurt his team’s performance. A plus-minus of +10 is typically reserved for players who are considered to be exceptional and have had a major impact on the game.
Factors That Affect Plus-Minus
Plus-minus is a cumulative statistic, meaning that it takes into account all of a player’s actions during a game. As such, there are several factors that can affect a player’s plus-minus rating, including:
• Offensive Contributions: This includes points scored, assists, rebounds and other offensive contributions.
• Defensive Contributions: This includes steals, blocks, deflections and other defensive contributions.
• Team Performance: A player’s plus-minus rating is heavily dependent on the performance of his team.
• Other Players on the Court: A player’s plus-minus rating is also affected by the performance of the other players on the court.
• Quality of Opponent: A player’s plus-minus rating is also affected by the quality of the opponent.
Conclusion
Plus-minus is a statistic used in basketball to measure a player’s overall impact on the game. It is a cumulative statistic that takes into account all of a player’s actions during a game, including offensive and defensive contributions, as well as the performance of the other players on the court. A good plus-minus typically falls somewhere between 0 and +10, with 0 being an average rating and +10 being an exceptional rating. In order to calculate a good plus-minus, it is important to take into account all of the factors that can affect a player’s rating, including offensive and defensive contributions, team performance, and quality of opponent.
