### What is Defensive Rebound Percentage?

Defensive Rebound Percentage (DRB%) is a basketball statistic that puts a player’s number of defensive rebounds in proportion to the total number of defensive rebounds available while they were in active play.

It is intended to be representative of part of a player’s defensive ability. Defensive rebounds are important to a team’s defensive strategy as they reduce the number of chances that the other team has to score on a second (or third) scoring attempt in a play.

### How to Calculate Defensive Rebound Percentage

Defensive Rebound Percentage (DRB%) is calculated as:

### Example

A player has 4 defensive rebounds and has played 41 minutes.

Their team has 32 defensive rebounds and has played 240 minutes.

The opposing team has 7 offensive rebounds.

Defensive Rebound Percentage (DRB%) = ((4 * (240/5)) / (41 * (32 + 7))) * 100%

Defensive Rebound Percentage (DRB%) = ((4 * 48) / (41 * 39)) * 100%

Defensive Rebound Percentage (DRB%) = (192 / 1599) * 100%

Defensive Rebound Percentage (DRB%) = 0.1201 * 100%

Defensive Rebound Percentage (DRB%) = 12.01%

Therefore, this player has a defensive rebound percentage of 12.01%.

### What counts as a Defensive Rebound in Basketball?

In basketball, a defensive rebound is recorded to the player who passes the ball to a teammate who then scores a basket.

In the NBA, assists that result in points from free throws (the pass is made to a player who is then fouled, followed by that player making a basket through a free throw) are not counted, however they are counted in FIBA (International Basketball Federation) matches.

### What counts as an offensive rebound in Basketball?

In basketball, an offensive rebounded is similar to a defensive rebound, but happens when the offensive team recovers the ball.

### What counts a minute played in Basketball?

A minute played is each minute of play that happens while the player is on the court.

Team minutes played are the total minutes played of all 5 players on the court at one time – one game of 48 minutes is a total of 240 minutes played.
