Player Efficiency Rating

Definition

Player Efficiency Rating (PER) is a comprehensive statistic designed to measure a basketball player's overall effectiveness on the court, combining various aspects of performance into a single number. This metric evaluates a player's contributions, including scoring, assists, rebounds, steals, blocks, and turnovers, thus providing a holistic view of their impact during games. By quantifying player performance, PER helps in making comparisons across players and understanding advanced analytics in sports.

1. PER was developed by basketball statistician John Hollinger as an attempt to summarize a player's statistical contributions in one easy-to-understand number.
2. The league-average PER is set at 15, meaning players above this threshold are considered above average while those below it are below average.
3. PER is pace-adjusted, meaning it accounts for the tempo of the game to ensure fairness when comparing players from different teams or eras.
4. Although PER is widely used, it has its limitations, such as not accounting for defense adequately and being sensitive to a player's usage rate.
5. PER is often utilized by analysts and teams to evaluate player performance, especially when making decisions related to trades and player contracts.
