Q & A

  • What is the significance of the term 'PI' in basketball analytics?

    -PI stands for Player Impact Estimate, which measures a player's contribution to a game, not just their team's production. It compares individual stats against the game's overall stats, with the number representing the percentage of the game impacted by that player.

  • How is the PI rating calculated?

    -The PI rating is calculated by measuring a player's stats against the stats for the entire game. It's a complex calculation, but essentially, it's a percentage that indicates how much of a single game a player has contributed to.

  • What does a high PI rating signify for a player?

    -A high PI rating signifies that a player has a significant impact on the game, contributing to a quarter of the game's events. Players with high PI ratings often end up being the MVP at the end of the season.

  • What is the difference between PE (Player Efficiency Rating) and PI?

    -PE measures a player's effect on the game versus their detriment to the game, focusing on their efficiency on the court and comparing them against their own team's players. PI, on the other hand, measures the player's overall contribution to the game.

  • How is the league average for PE determined?

    -The league average for PE is a flat 15, which means that every player is measured against every other player in the league. This standard does not change regardless of the perceived skill level of the league.

  • What does a PE rating of 35 indicate about a player's performance?

    -A PE rating of 35 indicates an all-time great season, a level of performance that has rarely been achieved in the history of the league.

  • What is the significance of Usage Rating in basketball analytics?

    -Usage Rating indicates how much a particular player is used by their team, measured by the percentage of team possessions that end with that player. It reflects the team's belief in the player as the best scoring option.

  • How does the leading Usage Rating in the league currently compare to historical data?

    -Joel Embiid is currently leading the league with a Usage Rating of 35.8%, which means a third of the Sixers' possessions end with him. If the season were to end today, this would be the highest Usage Rating of all time.

  • What does Net Rating measure and how is it calculated?

    -Net Rating measures the points scored by a team per 100 possessions while a player is on the floor, minus the points scored by the opposing team during the same period. It is often heavily influenced by the overall performance of the team.

  • Why might a player have a high Net Rating but not be an MVP candidate?

    -A player might have a high Net Rating due to playing against lesser competition or being part of a strong second unit, as in the case of Isaiah Joe of Oklahoma City, rather than being a standout player overall.

  • What is True Shooting Percentage and how does it account for different types of shots?

    -True Shooting Percentage is a metric designed to calculate a player's shooting efficiency by averaging free throws, field goals, and three-pointers based on their point value. It accounts for the fact that three-pointers are worth more than two-pointers and free throws.

  • What is Effective Field Goal Percentage and how does it differ from regular Field Goal Percentage?

    -Effective Field Goal Percentage is similar to regular Field Goal Percentage but takes into account that three-pointers are worth more than two-pointers, providing a more accurate measure of shooting efficiency.

  • What do per 36 stats represent and why are they used?

    -Per 36 stats extrapolate a player's statistics as if they played 36 minutes per game. They are used to compare players who do not get a lot of playing time or to make a case for a player's potential performance if they played more minutes.

  • How does Offensive Rating differ from Defensive Rating and what does it indicate?

    -Offensive Rating measures how many points a team would score with a player on the court for 100 possessions, taking into account the pace of the game. Defensive Rating measures how many points the opposing team would score against the player in the same scenario. A lower Defensive Rating indicates better defensive performance.

They provide a more nuanced understanding of a player's contribution and impact on the game. In the video's context, advanced stats are used to analyze player performance and team dynamics in a more detailed and quantitative manner, which is essential for understanding the modern approach to basketball analysis.
💡PI (Player Impact) rating
PI rating, or Player Impact rating, is an advanced statistic that measures a player's overall contribution to a game. It's defined as the percentage of a game's impact that can be attributed to a single player. The video emphasizes PI as a crucial metric, with the example of Nikola Jokic leading in PI, suggesting that he significantly influences the outcome of his team's games.
💡PE (Player Efficiency) rating
Player Efficiency rating is an advanced metric that evaluates a player's overall performance on the court. It takes into account both positive contributions and potential drawbacks. The video explains that PE is measured on a league-wide scale, with an average of 15, making it a benchmark for assessing player performance relative to the entire league.
💡Usage rating
Usage rating indicates the proportion of a team's offensive plays that end with a specific player being involved, either through a shot attempt, turnover, or free throw. The video script mentions that a high usage rate does not necessarily equate to being a good player, but it does suggest that the team relies on that player as a primary scoring option.
💡Net rating
Net rating is a statistic that measures a team's point differential per 100 possessions when a player is on the court. It reflects the team's scoring efficiency and defensive effectiveness while the player is active. The video uses Isaiah Joe's high net rating as an example, indicating that his team outscores opponents significantly when he plays, even though he is not an MVP candidate.
💡True shooting percentage
True shooting percentage is a metric designed to provide a more accurate measure of shooting efficiency by accounting for field goals, three-pointers, and free throws based on their point values. The video clarifies that this percentage levels the playing field by giving more weight to higher-scoring shots, such as three-pointers, compared to free throws.
💡Effective field goal percentage
Effective field goal percentage is similar to traditional field goal percentage but gives extra value to made three-pointers because they are worth more points. This metric adjusts a player's shooting percentage to reflect the varying point values of shots, providing a more comprehensive view of shooting efficiency.
💡Per 36 stats
Per 36 stats are a way of standardizing player statistics to a per-game basis of 36 minutes. This allows for a fair comparison of players who may not play the same amount of minutes. The video mentions per 36 stats in the context of discussing a player's potential output if they were to play more minutes.
💡Offensive rating
Offensive rating is a statistic that measures the number of points a team would score with a player on the court for 100 possessions. It takes into account the pace of the game, which means a faster-paced team might have a higher offensive rating due to more scoring opportunities. The video points out that the top offensive rating players are part of a cohesive starting lineup, indicating the importance of team dynamics in this metric.
💡Defensive rating
Defensive rating is the counterpart to offensive rating, indicating the number of points the opposing team would score against a player's team for every 100 possessions. A lower defensive rating is preferable, as it signifies that the player contributes to limiting the opponent's scoring. The video highlights Kyle Anderson's low defensive rating as a testament to his defensive prowess.
