Defensive rating or defensive efficiency is a statistic used in basketball to measure an individual player's efficiency at preventing the other team from scoring points. It was created by author and statistician Dean Oliver.


The formula is: Defensive Player Rating = (Players Steals*Blocks) + Opponents Differential= 1/5 of possessions - Times blown by + Deflections * OAPDW( Official Adjusted Players Defensive Withstand). This stat can't be influenced by the defense of a player's teammates.
