GLOSSARY
In this glossary, you can find the definitions, translations, and abbreviations of all the stats used in basketball. You can find a chapter of “Learn a Stat” for some advanced stats, to better understand theories and formulas of these stats, all supported by some examples for the most complex ones: you can find the link on the name of the stats with the dedicated chapter.
Some general concepts before going into detail; if a stats can refer to different elements, prefixes are used for more comprehensive accuracy:
- Te: team stat;
- Opp: opponent stat;
- Lg: league stat;
- No prefix: player stat;
If you are using the average value “per game” you can find the suffix “/G” or “PG”.

+/-
PLUS MINUS
The total amount of points scored and allowed by a player’s team while he/she is on the field. It is a very interesting statistic because it tends to show the impact of a player on the court. It can be negative if the team allows more points than made.
POSS
POSSESSION
Learn a Stat: Possessions and Pace
The number of total possessions played during the entire game. Be careful though, because possession for statistics is not what we usually mean. In statistical terms, possession can end in only 3 ways:
- The offensive team scores a basket (from the field or from the free throw line);
- The offensive team loses the ball;
- The defensive team grabs a defensive rebound after a missed shot (from the field or from the free throw line);
The number of possessions is not provided in the traditional box score: Dean Oliver has therefore created a formula that allows estimating the number of possessions.
Poss = FGA – OR + TO + 0.44 * FTA
The definition and the formula show that an offensive rebound does not generate a new possession. Thanks to this equation you can find an estimate of the number of possessions played by a team. To obtain a more accurate number, the average of the two teams’ possessions can be calculated. The 0,44 factor estimates the number of trips to the FT line (no tech and and-one). If this value is known, it’s better to use it.
SHOOTING CHANCES; PLAYS
SHOOTING CHANCES; PLAYS
The possession is the number of times a team ended its possession of the ball. However, as we have just seen, there could be more shots during a possession. If you want to know how many times a team had the chance to score, you refer to Shooting Chances.
Shooting Chances= FGA + TO + 0.44 * FTA
The 0,44 factor estimates the number of trips to the FT line (no tech and and-one). If this value is known, it’s better to use it. Shooting chances are equal to the sum of the individual possessions of all players.
PACE
PACE
Learn a Stat: Possessions and Pace
Other terms: Pace Factor
The pace is the stat that allows you to compare the number of possessions over the 40 (or 48) minutes and understand the average game speed of a team. Why is it better to compare Pace and not Possessions? Because of overtime. Pace makes possible to compare the game speed taking into account this particular situation (otherwise possessions will be always higher for a team that has played overtime).
SoS
STRENGTH OF SCHEDULE
Learn a Stat: Strength of Schedule
Strength of Schedule is a stat that is rarely used in Europe. This is because in our leagues schedules are designed in a way that each team plays the same number of matches and they all play against all, without distinction. The Strength of Schedule is a value that shows the difficulty of the calendar played so far (it is therefore not a predictive statistic) when the various calendars show different numbers of games and/or different opponents, as happens for example in NBA. In this way, through the SoS value it is possible to understand which teams have faced a more or less hard schedule, in order to evaluate their stats taking into account the more or less strength of schedule.
ORTG; OFF RTG
TEAM OFFENSIVE RATING
Learn a Stat: Team Offensive, Defensive, and Net Rating
It is the team’s offensive efficiency value. This stat gives an estimate of the points made by a team on a basis of 100 possessions. It does not provide an absolute value: the team’s value must always be compared with the average value of the league (i.e. the average of all the Off Rtg of the teams in the championship). This is because a team with a value of 115 will be phenomenal if the league average is 100, but will be normal if the average is 110.
DRTG; DEF RTG
TEAM DEFENSIVE RATING
Learn a Stat: Team Offensive, Defensive, and Net Rating
It is the team’s defensive efficiency value. This stat gives an estimate of the points allowed by a team on the basis of 100 possessions. It does not provide an absolute value: the team’s value must always be compared with the average value of the league. The league defensive rating average will be identical to the league offensive rating average.
NRTG; NET RTG
TEAM NET RATING
Learn a Stat: Team Offensive, Defensive, and Net Rating
It is the difference between Team Offensive Rating and Team Defensive Rating.
OFF PPP
OFFENSIVE POINT PER SHOOTING CHANCES
It is the ratio between points scored and shooting chances. It shows the efficiency of a team to score compared to the total chances got.
DEF PPP
DEFENSIVE POINT PER SHOOTING CHANCES
It is the ratio between points allowed and shooting chances. It shows the efficiency of a team to denay an opponent to score.
ORTG; OFF RTG; IND OFF RTG
INDIVIDUAL OFFENSIVE RATING
Learn a Stat: Individual Offensive Rating
Other terms: Player Offensive Rating
The individual Offensive Rating is the value of points produced by a player on 100 possessions. The calculation for the player’s offensive rating requires the use of different formulas that you can consult in the dedicated post: briefly, the stat takes into account the baskets from the field made and attempted, the free throws made and attempted, the assists made, the turnovers and offensive rebounds grabbed, with different weights depending on the contribution and team performance. As for team evaluations, it is better to compare the value of the individual player with the League average. In general, the higher the value, the better the player’s offensive contribution will be.
DRTG; DEF RTG, IND DEF RTG
INDIVIDUAL DEFENSIVE RATING
Learn a Stat: Individual Defensive Rating
Other terms: Player Defensive Rating
The Defensive Rating defines the number of points allowed by the player to the opposing team on 100 possessions. This stat is made up of two factors. The first takes into account some player’s contributions: defensive rebounds, steals, blocks, and fouls committed. The second term is more difficult to calculate because it consists of a series of data that are not found in the normal box-scores. These data are:
- Opponent’s turnovers forced by the player (without stealing the ball);
- Opponent’s missed shots contested by the player (but not blocked);
- Opponent’s missed free throws after being sent to the line by the defender;
- Opponent’s shots made allowed by the player;
Since these data are rarely available, Oliver made some approximations in order to obtain them: it is assumed that the five defenders on the field are equally good at forcing turnovers and contested shots. Therefore, opponents’ missed shots and turnovers are divided according to players’ minutes played. This distribution is fairly rough, but it is necessary because of the limited data available. If, for example, a team puts in three excellent defenders and two bad ones, these two will get statistical benefits for their Def Rtg value, despite being bad defenders.
Furthermore, this value is also influenced by the team’s Defensive Rating: this leads to having medium-low individual values for good defenders who play in teams with mediocre defenses. The final value remains reliable, but these approximations must be taken into account when evaluating individual Defensive Rating. As you have understood by now, all the considerations made for the other ratings are still valid: it’s better to compare the values with the League average.
NRTG; NET RTG
INDIVIDUAL NET RATING
Other terms: Player Net Rating
The difference between individual Offensive Rating and Individual Defensive Rating: in other words, it is the player’s actual contribution when he is on the court. If the value is greater than zero, the presence on the field will be positive; otherwise, it will be negative (he allowed more points than he made). Although it reminds the Plus-Minus definition, it provides different information.
USG%
USAGE PERCENTAGE
Learn a Stat: Shooting percentages and Usage
It is an estimate of the percentage of the possessions used by a player compared to the team’s ones. The higher the value, the greater the number of possessions concluded by the player.
2P 100POSS
TWO POINT ATTEMPTED PER 100 POSSESSIONS
It is the estimate of 2 point shots attempted on 100 offensive possessions. An offensive possession can be ended only by a shot or a turnover. Useful data for comparing shot distribution.
3P 100POSS
THREE-POINT ATTEMPTED PER 100 POSSESSIONS
It is the estimate of 3 point shots attempted on 100 offensive possessions. An offensive possession can be ended only by a shot or a turnover. Useful data for comparing shot distribution.
FT 100POSS
FREE THROW ATTEMPTED PER 100 POSSESSIONS
It is the estimate of free throws attempted on 100 offensive possessions. An offensive possession can be ended only by a shot or a turnover. Useful data for comparing shot distribution.
SHOOTING FREQ (RIM, PAINT, MID, C3, L3)
SHOOTING FREQUENCY
For each zone (rim: restricted area, paint: paint, mid: inside the 3-point line but outside the paint, C3: corner 3’s, L3: long 3’s), it is possible to calculate the shooting frequency, i.e. the percentage of attempts from that zone. At the denominator, there could be either the total shots attempted (FGA) or the Shooting Chances. If Shooting Chances are used, 100% will be reached by summing up all the shooting frequencies, FT Ratio, and TO%.
PPS (RIM, PAINT, MID, C3, L3)
POINT PER SHOT
For each zone (rim: restricted area, paint: paint, mid: inside the 3-point line but outside the paint, C3: corner 3’s, L3: long 3’s), it is possible to calculate the shooting efficiency. The formula is the ratio between points scored from that zone and attempts from that zone.
FT Ratio
FT Ratio
Percentage of times a Shooting Chances ended at the FT line (no tech and and-one). It’s the ratio between trips to the FT line and Shooting Chances.
OR%; OREB%
OFFENSIVE REBOUND PERCENTAGE
Learn a Stat: Rebound Percentages
The percentage of offensive rebounds grabbed by the player/team during the game. Therefore, the opponent’s defensive rebounds are also taken into account. There are specific versions of this stat: OR% (2P), OR% (3P), OR% (FT). Meaning and calculation are the same, but you have to take into account only the events after a missed 2-point shot, 3-point shot, or free throw.
DR%; DREB%
DEFENSIVE REBOUND PERCENTAGE
Learn a Stat: Rebound Percentages
The percentage of defensive rebounds grabbed by the player/team during the game. Therefore, the opponent’s offensive rebounds are also taken into account. There are specific versions of this stat: DR% (2P), DR% (3P), DR% (FT). Meaning and calculation are the same, but you have to take into account only the events after a missed 2-point shot, 3-point shot, or free throw.
TR%; TREB%
TOTAL REBOUND PERCENTAGE
Learn a Stat: Rebound Percentages
The percentage of total rebounds grabbed by the player/team during the game. Therefore, the opponent’s total rebounds are also taken into account.
AST%
ASSIST PERCENTAGE
Learn a Stat: Assists and turnovers
The percentage of baskets “assisted” by the player/team. It makes clear how much a player/team passes the ball to others. There are specific versions of this stat: AST% (2P), AST% (3P), AST% (FT). Meaning and calculation are the same, but you have to take into account only the events after a 2-point shot, 3-point shot, or free throw.
AST / TO
ASSIST TO TURNOVER RATIO
The relationship between assists and turnovers. Shows the number of assists made per lost ball. The higher the number, the more assists the player/team makes between one turnover and the next one.
AST RATIO
ASSIST RATIO
Learn a Stat: Assists and turnovers
The number of assists made by the player/team per 100 possessions. Basically the higher the value, the more assists the player/team makes against fewer attempts.
TO RATIO; TO%; TOV RATIO; TOV%
TURNOVER RATIO
Learn a Stat: Assists and turnovers
The player version is the ratio between turnovers and individual possessions. The team version is the ratio between turnover and Shooting Chances.
ST%
STEAL PERCENTAGE
Learn a Stat: Steals and blocks
The percentage of balls stolen by the player/team related to the total opponent’s possessions.
BLK%
BLOCK PERCENTAGE
Learn a Stat: Steals and blocks
The percentage of 2-point shots blocked by the player/team.
PF 100 POSS
PERSONAL FOULS PER 100 POSSESSIONS
It shows the fouls committed by the player/team for every 100 team possessions. With this statistic, it is possible to compare fouls committed on the same basis.
DF 100 POSS
DRAWN FOULS PER 100 POSSESSIONS
It shows the fouls drawn by the player/team for every 100 team possessions. With this statistic, it is possible to compare fouls drawn on the same basis.
PSF FREQ
PERSONAL SHOOTING FOUL FREQUENCY
It’s the ratio between shooting fouls and total fouls committed.
DSF FREQ
DRAWN SHOOTING FOUL FREQUENCY
It’s the ratio between drawn shooting fouls and total drawn fouls.
EFG%
EFFECTIVE FIELD GOAL PERCENTAGE
Learn a Stat: Shooting percentages and Usage
The percentage of achievement of a player/team is calculated considering the 3-shot made with a weight equal to 1.5 times of a 2-point shot. In this way, you can compare the field percentages of internal players and shooters, without the latter being affected too much by the greater difficulty of 3-point shooting.
TS%
TRUE SHOOTING PERCENTAGE
Learn a Stat: Shooting percentages and Usage
The percentage of the total shot that takes into account the points made and all the shooting attempts (from the field and from the free throw line). In other words, it is the percentage by which a player/team ends his possessions positively.
KILLS
KILLS
The Kills are another way to evaluate the defensive effort of the team. A kill is equal to three consecutive stops of the opponent’s offense. To get a stop, the opponent’s possession has to end with a turnover or with a missed shot and a defensive rebound. In other words, the opponent has to not score for three possessions in a row.
PER
PLAYER EFFICIENCY RATING
Learn a Stat: Player Efficiency Rating (PER)
PER is a more sophisticated version of the classic Efficiency. In fact, it takes into account almost all the parameters of the efficiency, but, through a series of factors and the introduction of team and league pace, it creates a unique basis for comparing players’ performance. The reference value is 15, which indicates the “average” player. Given this value, it is possible to create a univocal evaluation scale (PER is, therefore, an absolute value):
More than MVP: 43 o più
MVP: 33 – 42,9
Almost MVP: 30 – 32,9
Less than an MVP: 25 – 29,9
All-Star player: 22,5 – 24,9
Possible All-Star player: 20 – 22,4
Second offensive option: 18 – 19,9
Third offensive option: 16,5 – 17,9
Average player: 15 – 16,4
Bench player: 13 – 14,9
Always sit on the bench: 11 – 12,9
Barely a player: 9 – 10,9
Not a player at all: 0 – 8,9
WS
WIN SHARE
Learn a Stat: Win Share
Win Share is the statistic that allows you to understand who among the players on the roster contributes most to the victories. The principle is as follows: each team’s victory is considered to be equal to 1 Win Share. The individual players will have contributed differently to the victories: this statistic estimates the contribution to the victory in numerical terms. The sum of all players’ Win Shares of a team is more or less equal to the number of W obtained by the team. The Win Share is calculated by summing two contributions: the Offensive Win Share and the Defensive Win Share.
OWS
OFFENSIVE WIN SHARE
Learn a Stat: Win Share
This value mainly depends on the player’s Points Production and his possessions used. By combining these values with the league averages we obtain the Offensive Win Share.
DWS
DEFENSIVE WIN SHARE
Learn a Stat: Win Share
For this statistic, the player’s Defensive Rating and his minutes played are taken into account. It gives an estimate of the player’s defensive contribution to the victory.
WS PER 40 MIN
WIN SHARE PER 40 MINUTES
Learn a Stat: Win Share
Since the Win Share is a stat based on season total, it provides the hypothetical total number of games won by a player. For a better comparison, the total Win Share values are divided by player’s minutes played and multiplied for 40 (or 48) minutes. By doing this, you can compare the various Win Shares, without having to take into account games and minutes played.
BPM
BOX PLUS MINUS
Learn a Stat: Box Plus Minus and VORP
It’s the evolution of the classic Plus Minus. If the +/- is the sum of the points scored and allowed by the team while the player is on the court, the BMP normalizes the contribution on 100 possessions. In this way, you can make a comparison of the contribution of all players. The BPM gives the player’s points produced compared to the average League level, set at 0: obviously the higher the value, the better the player’s contributions. Normally, a value of +5 is very good, -5 very bad; -2 is the reference player’s value, used for the calculation of the VORP.
OBMP; OFFBMP
OFFENSIVE BOX PLUS MINUS
Learn a Stat: Box Plus Minus and VORP
It is a statistic that has the same meaning as the previous one, but the contributions considered in the calculation are factored with coefficients that take into account only the offensive phase.
DBMP; DEFBMP
DEFENSIVE BOX PLUS MINUS
Learn a Stat: Box Plus Minus and VORP
It is a statistic that has the same meaning as the previous one and is obtained by subtracting the OffBMP from the BMP. It, therefore, provides the player’s contribution taking into account only the defensive phase.
VORP
VALUE OVER REPLACEMENT PLAYER
Learn a Stat: Box Plus Minus and VORP
If the BPM provides the contribution generated by a player, the VORP allows understanding what the player’s contribution is by comparing it to the replacement player’s contribution. The VORP, therefore, takes into account the minutes and games played and considers the value -2 as the BPM value for the “Replacement Player”. VORP is the most reliable statistic to understand which are the players who contribute substantially to their team’s victories.
