## Introduction to Advanced Basketball Stats

**Table of Contents**hide

Advanced basketball stats are a great way to measure a player’s performance and compare it to their peers. Advanced basketball stats include player efficiency rating (PER), win shares (WS), offensive rating (ORtg), defensive rating (DRtg), true shooting percentage (TS%), assist-to-turnover ratio (ATO), and box plus/minus (BPM). These metrics provide a more detailed look at a player’s individual performance and how it affects the team as a whole.

## Why Are Advanced Basketball Stats Important?

Advanced basketball stats are important because they provide a more detailed look at a player’s performance than traditional stats like points per game or rebounds per game. Advanced basketball stats can help teams identify players who are making the most efficient use of their time on the court. Teams can use these metrics to determine which players are playing the most effectively, and which players may need to be replaced or given more playing time.

## Player Efficiency Rating (PER)

Player efficiency rating (PER) is a metric that measures a player’s overall efficiency. It takes into account a players shooting, rebounding, passing, and other offensive and defensive contributions. PER is calculated by taking a player’s total points, rebounds, assists, steals, blocks, and turnovers and dividing it by the number of minutes the player has played.

### Calculating PER

To calculate a player’s PER, you’ll need to gather the following data: points, rebounds, assists, steals, blocks, and turnovers.

First, add up the number of points, rebounds, assists, steals, blocks, and turnovers the player has had in a game or season. Then, divide that total by the total number of minutes the player has played. Finally, multiply the resulting number by a factor of 15.2 to get the player’s PER.

**For example:** A player has scored 30 points, had 10 rebounds, 5 assists, 3 steals, 2 blocks, and 2 turnovers in 40 minutes of play. Their PER would be calculated as follows:

30 + 10 + 5 + 3 + 2 + 2 = 52

52 / 40 = 1.3

1.3 * 15.2 = 19.76

The player’s PER would be 19.76.

Win shares (WS) is a statistic that measures how much a player contributes to their team’s success in terms of wins. This statistic takes into account the player’s offensive and defensive contributions, as well as their overall team performance.

To calculate a player’s win shares, you’ll need to gather the following data: points, rebounds, assists, steals, blocks, and turnovers.

First, add up the number of points, rebounds, assists, steals, blocks, and turnovers the player has had in a game or season. Then, divide that total by the total number of minutes the player has played. Finally, multiply the resulting number by a factor of 2.7 to get the player’s win shares.

**For example:** A player has scored 30 points, had 10 rebounds, 5 assists, 3 steals, 2 blocks, and 2 turnovers in 40 minutes of play. Their win shares would be calculated as follows:

30 + 10 + 5 + 3 + 2 + 2 = 52

52 / 40 = 1.3

1.3 * 2.7 = 3.51

The player’s win shares would be 3.51.

## Offensive Rating (ORtg)

Offensive rating (ORtg) is a metric that measures a player’s efficiency on the offensive end of the court. It takes into account a players shooting, passing, and other offensive contributions. ORtg is calculated by taking a player’s total points, assists, and turnovers, and dividing it by the number of possessions the player has used.

### Calculating ORtg

To calculate a player’s ORtg, you’ll need to gather the following data: points, assists, and turnovers.

First, add up the number of points, assists, and turnovers the player has had in a game or season. Then, divide that total by the total number of possessions the player has used. Finally, multiply the resulting number by a factor of 100 to get the player’s ORtg.

**For example:** A player has scored 30 points, had 5 assists, and 2 turnovers in 20 possessions. Their ORtg would be calculated as follows:

30 + 5 + 2 = 37

37 / 20 = 1.85

1.85 * 100 = 185

The player’s ORtg would be 185.

## Defensive Rating (DRtg)

Defensive rating (DRtg) is a metric that measures a player’s efficiency on the defensive end of the court. It takes into account a players defensive contributions such as steals, blocks, and defensive rebounds. DRtg is calculated by taking a player’s total defensive rebounds, steals, and blocks, and dividing it by the number of possessions the player has been on the court.

### Calculating DRtg

To calculate a player’s DRtg, you’ll need to gather the following data: defensive rebounds, steals, and blocks.

First, add up the number of defensive rebounds, steals, and blocks the player has had in a game or season. Then, divide that total by the total number of possessions the player has been on the court. Finally, multiply the resulting number by a factor of 100 to get the player’s DRtg.

**For example:** A player has had 7 defensive rebounds, 3 steals, and 2 blocks in 20 possessions. Their DRtg would be calculated as follows:

7 + 3 + 2 = 12

12 / 20 = 0.6

0.6 * 100 = 60

The player’s DRtg would be 60.

## True Shooting Percentage (TS%)

True shooting percentage (TS%) is a metric that measures a player’s ability to convert shots into points. It takes into account a players shooting percentage from all areas of the court (free throw, 2-point, and 3-point). TS% is calculated by taking a player’s total points, free throws attempted, 2-point field goals attempted, and 3-point field goals attempted and dividing it by the total number of shots attempted.

### Calculating TS%

To calculate a player’s TS%, you’ll need to gather the following data: points, free throws attempted, 2-point field goals attempted, and 3-point field goals attempted.

First, add up the number of points, free throws attempted, 2-point field goals attempted, and 3-point field goals attempted the player has had in a game or season. Then, divide that total by the total number of shots attempted. Finally, multiply the resulting number by a factor of 100 to get the player’s TS%.

**For example:** A player has scored 30 points, had 10 free throws attempted, 20 2-point field goals attempted, and 10 3-point field goals attempted in 40 shots attempted. Their TS% would be calculated as follows:

30 + 10 + 20 + 10 = 70

70 / 40 = 1.75

1.75 * 100 = 175

The player’s TS% would be 175.

## Assist-To-Turnover Ratio (ATO)

Assist-to-turnover ratio (ATO) is a metric that measures a player’s ability to make good decisions with the ball. It takes into account a players assists and turnovers. ATO is calculated by taking a player’s total assists and dividing it by the total number of turnovers.

### Calculating ATO

To calculate a player’s ATO, you’ll need to gather the following data: assists and turnovers.

First, add up the number of assists and turnovers the player has had in a game or season. Then, divide the total number of assists by the total number of turnovers. This will give you the player’s ATO.

**For example:** A player has had 5 assists and 2 turnovers in a game. Their ATO would be calculated as follows:

5 / 2 = 2.5

The player’s ATO would be 2.5.

## Box Plus/Minus (BPM)

Box plus/minus (BPM) is a metric that measures a player’s overall contribution to their team’s success. It takes into account a players offensive and defensive contributions, as well as their overall team performance. BPM is calculated by taking a player’s total points, rebounds, assists, steals, blocks, and turnovers and dividing it by the total number of possessions the player has used.

### Calculating BPM

To calculate a player’s BPM, you’ll need to gather the following data: points, rebounds, assists, steals, blocks, and turnovers.

First, add up the number of points, rebounds, assists, steals, blocks, and turnovers the player has had in a game or season. Then, divide that total by the total number of possessions the player has used. Finally, multiply the resulting number by a factor of 100 to get the player’s BPM.

**For example:** A player has scored 30 points, had 10 rebounds, 5 assists, 3 steals, 2 blocks, and 2 turnovers in 20 possessions. Their BPM would be calculated as follows:

30 + 10 + 5 + 3 + 2 + 2 = 52

52 / 20 = 2.6

2.6 * 100 = 260

The player’s BPM would be 260.

## Conclusion

Advanced basketball stats are a great way to measure a player’s performance and compare it to their peers. Advanced basketball stats include player efficiency rating (PER), win shares (WS), offensive rating (ORtg), defensive rating (DRtg), true shooting percentage (TS%), assist-to-turnover ratio (ATO), and box plus/minus (BPM). These metrics provide a more detailed look at a player’s individual performance and how it affects the team as a whole. With these metrics, teams can identify players who are making the most efficient use of their time on the court and make more informed decisions about how to best manage their rosters.
