Offensive Rebound Percentage (ORB%) Calculator

The formula for calculating Offensive Rebound Percentage is: (Player Offensive Rebounds * (Team Minutes / 5)) / (Player Minutes * (Team Offensive Rebounds + Opponent Defensive Rebounds)) * 100. This formula estimates the percentage of offensive rebounding opportunities the player converted while on the court.

Offensive Rebound Percentage estimates the proportion of available offensive rebounds a player secures while on the court. It adjusts for playing time and opportunities, allowing for fair comparisons between players with different minutes or on teams with different paces. A higher ORB% indicates that a player is more effective at grabbing offensive rebounds when the opportunity arises. This statistic is particularly valuable for evaluating big men and other players who are expected to contribute on the offensive glass.

ORB% is crucial for understanding a player's ability to create second-chance opportunities for their team. Players with high ORB% can significantly impact the game by extending possessions and providing additional scoring chances. This metric is particularly valuable for evaluating centers and power forwards, but it can offer insights into the rebounding abilities of players at any position.

Offensive Rebound Percentage has gained prominence in basketball analytics as a way to measure a player's ability to create second-chance opportunities, independent of playing time or team pace.

As basketball analytics has evolved, ORB% has become an important tool for evaluating rebounding ability in the context of a player's opportunities. It's part of a broader trend in sports analytics towards contextualizing individual statistics within team performance and playing time.

While ORB% provides insight into a player's offensive rebounding ability, it doesn't account for the quality or impact of those rebounds. It also doesn't consider tactical decisions, such as a team choosing to prioritize transition defense over offensive rebounding.

If a player has 100 offensive rebounds in 2000 minutes, with the team having 800 offensive rebounds, opponents having 2500 defensive rebounds, and the team playing 19680 total minutes, their Offensive Rebound Percentage would be calculated as follows: (100 * (19680 / 5)) / (2000 * (800 + 2500)) * 100 ≈ 11.8%.

Players like Dennis Rodman, Moses Malone, and Andre Drummond have historically posted very high Offensive Rebound Percentages, often exceeding 15% or even 20% in their peak seasons.
