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. [1] Oliver introduced the defensive rating statistic in his 2004 book, Basketball on Paper. [2]
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 be influenced by the defense of a player's teammates.
Gar Heard's 95.30 defensive rating is the NBA's all-time career record. [3] Ben Wallace's 87.48 defensive rating in 2003–2004 is the single-season record. [4]

The player efficiency rating (PER) is John Hollinger's all-in-one basketball rating, which attempts to collect or boil down all of a player's contributions into one number. Using a detailed formula, Hollinger developed a system that rates every player's statistical performance.
Advanced statistics in basketball refers to the analysis of basketball statistics using objective evidence. APBRmetrics takes its name from the acronym APBR, which stands for the Association for Professional Basketball Research.
Field goal percentage in basketball is the ratio of field goals made to field goals attempted. Its abbreviation is FG%. Although three-point field goal percentage is often calculated separately, three-point field goals are included in the general field goal percentage. Instead of using scales of 0 to 100%, the scale .000 to 1.000 is commonly used. A higher field goal percentage denotes higher efficiency. In basketball, a FG% of .500 (50%) or above is considered a good percentage, although this criterion does not apply equally to all positions. Guards usually have lower FG% than forwards and centers. Field goal percentage does not completely tell the skill of a player, but a low field goal percentage can indicate a poor offensive player or a player who takes many difficult shots. In the NBA, center Shaquille O'Neal had a high career FG% because he played near the basket making many high percentage layups and dunks. Guard Allen Iverson often had a low FG% because he took the bulk of his team's shot attempts, even with high difficulty shots.
Statistics in basketball are kept to evaluate a player's or a team's performance.
Lawrence Dean Oliver is an American statistician and coach. Oliver is a prominent contributor to the advanced statistical evaluation of basketball. He is the author of Basketball on Paper, the former producer of the defunct Journal of Basketball Studies. More recently, Oliver has served in front office roles with the Sacramento Kings, Seattle SuperSonics and Denver Nuggets of the NBA. In October 2015 Dean Oliver joined TruMedia Networks as Vice President of Data Science. TruMedia Networks is an engineering firm specializing in sports analytics solutions for leagues, franchises and media partners, and says of Oliver in a press release announcing Dean Oliver's hiring, "Oliver was most recently in the front office of the Sacramento Kings and is considered one of the best minds in the world of sports analytics."
Offensive proficiency rating or offensive productive efficiency is a statistic used in basketball to measure either a team's offensive performance or an individual player's efficiency at producing points for the offense by approximating the number of points generated by a team or individual over 100 possessions. It was created by author and statistician Dean Oliver.
The 50–40–90 club is a statistical achievement used to distinguish players as excellent shooters in the National Basketball Association (NBA), NBA G League, Women's National Basketball Association (WNBA), and men's college basketball. It requires a player to achieve the criteria of 50% field goal percentage, 40% three-point field goal percentage, and 90% free throw percentage over the course of a regular season, while meeting the minimum thresholds to qualify as a league leader in each category.
In professional basketball, the most commonly used statistical benchmark for comparing the overall value of players is called efficiency. It is a composite basketball statistic that is derived from basic individual statistics: points, rebounds, assists, steals, blocks, turnovers, and shot attempts. In theory, efficiency accounts for both a player's offensive contributions and their defensive contributions, but it is generally thought that efficiency ratings favor offense-oriented players over those who specialize in defense, as defense is difficult to quantify with currently tabulated statistics.
The IBM Award was an award given out to National Basketball Association players from 1984 to 2002. The award was sponsored and calculated by technology company IBM and was determined by a computer formula, which measured a player's statistical contribution to his team. The player with the best contribution to his team in the league received the award. The first recipient was Magic Johnson of the Los Angeles Lakers, and the final recipient was Tim Duncan of the San Antonio Spurs.
Performance Index Rating (PIR) is a basketball mathematical statistical formula that is used by the Euroleague Basketball Company's first and second tier competitions, the EuroLeague and the EuroCup, as well as various European national domestic and regional leagues. It is a part of the Tendex basketball rating system. It is also variously referred to as Performance Index Ranking, Rating, Ranking, Evaluation, Valuation, and Efficiency. It is similar to, but not exactly the same as, the NBA's Efficiency (EFF) stat.
Adjusted Plus-Minus is a basketball analytic that attempts to predict the impact of an individual player on the scoring margin of a game by controlling for the rest of the players on the court at any given time. The metric is derived using play-by-play data to keep track of all substitution and possession ending actions. It was first implemented by the Dallas Mavericks in the early 2000s after owner Mark Cuban commissioned data scientists Jeff Sagarin, Wayne Winston, and Dan Rosenbaum, who developed the metric alongside their WINVAL conversion to aid in player salary determination. In combination with other innovations, this gave the Mavericks one of the most progressive front offices in the league at the time. Since APM's creation several derivative metrics attempting to improve on the skeleton have been created.
