• OBPR: Offensive Bayesian Performance Rating reflects the offensive value a player brings to his team when he is on the court. This rating incorporates a player's individual efficiency stats and on-court play-by-play impact, and also accounts for the offensive strength of other teammates on the floor with him, along with the defensive strength of the opponent's players on the floor. OBPR is interpreted as the number of offensive points per 100 possessions above D1 average expected by the player's team if the player were on the court with 9 other average players. A higher rating is better.
• DBPR: Defensive Bayesian Performance Rating reflects the defensive value a player brings to his team when he is on the court. This rating incorporates a player's individual efficiency stats and on-court play-by-play impact, and also accounts for the defensive strength of other teammates on the floor with him, along with the offensive strength of the opponent's players on the floor. DBPR is interpreted as the number of defensive points per 100 possessions better than (below) D1 average expected to be allowed by the player's team if the player were on the court with 9 other average players. A higher rating is better.
• BPR: Bayesian Performance Rating is the sum of a player's OBPR and DBPR. This rating is the ultimate measure of a player's overall value to his team when he is on the floor. BPR is interpreted as the number of points per 100 possessions better than the opponent the player's team is expected to be if the player were on the court with 9 other average players. A higher rating is better.
• Change: Improvement in BPR over the last 30 days.
• Off Poss: Number of offensive possessions played.
• Def Poss: Number of defensive possessions played.
• Box OBPR: Box Offensive Bayesian Performance Rating is an estimate of a player's offensive value, based only on his individual stats. This serves as a prior starting point when calculating OBPR.
• Box DBPR: Box Defensive Bayesian Performance Rating is an estimate of a player's defensive value, based only on his individual stats. This serves as a prior starting point when calculating DBPR.
• Box BPR: Box Bayesian Performance Rating is the sum of a player's Box OBPR and Box DBPR. This rating is an estimate of a player's overall value, based only on his individual stats.
• Adj Team Off Eff: Team offensive efficiency (points scored per 100 possessions) with player on the court, adjusted for strength of opponent players faced. A higher value is better.
• Adj Team Def Eff: Team defensive efficiency (points allowed by opponent per 100 possessions) with player on the court, adjusted for strength of opponent players faced. A lower value is better.
• Adj Team Eff Margin: Difference between adjusted team offensive and adjusted defensive efficiency with player on the court. A higher value is better.
• +/-: Number of points scored for the player's team with him on the court, minus the number of points scored by the opponent with him on the court.
• Position: An estimate of a player's position based on his individual stats and team contributions. An estimated position of 1 corresponds to being a point guard, and a 5 corresponds to being a center. This estimate comes from Daniel Myers' Box Plus Minus 2.0.
• Role: An estimate of a player's offensive role based on his individual stats and team contributions. An estimated role of 1 corresponds to being the "creator" in the offense, and a 5 corresponds to being the "receiver". This estimate comes from Daniel Myers' Box Plus Minus 2.0.
• Avg Opp BPR: The average BPR of the opponent's players on the floor at the same time as the player. A higher rating indicates that the player played against tougher opposition.
• Position: An estimate of a player's position based on his individual stats and team contributions. An estimated position of 1 corresponds to being a point guard, and a 5 corresponds to being a center. This estimate comes from Daniel Myers' Box Plus Minus 2.0.
• Role: An estimate of a player's offensive role based on his individual stats and team contributions. An estimated position of 1 corresponds to being the "creator" in the offense, and a 5 corresponds to being the "receiver". This estimate comes from Daniel Myers' Box Plus Minus 2.0.

BPR Interpretation Example: If Jimmer Fredette had an Offensive BPR of 4.5, a Defensive BPR of -0.5, and a BPR of 4.0, this would mean the following: If Fredette were on the court with 9 other D1 average players, his team's offense would be 4.5 points per 100 possessions better than average, or if he were not on the floor and were replaced by another D1 average player. Similarly, his team's defense would be expected to be 0.5 points per 100 possessions worse (conceding 0.5 PP100 more) while he's on the floor. Overall, his team would be expected to outscore the opponent by 4.0 points in a 100 possession game.

Glossary:

• Team Off Eff: Team offensive efficiency (points per possession scored) with those two player on the court at the same. A higher value is better.
• Team Def Eff: Team defensive efficiency (points per possessions by opponent) with those two players on the court at the same time. A lower value is better.
• Team Eff Margin: Difference between team offensive and defensive efficiency with those two players on the court at the same time. A higher value is better.
• Off Poss: Number of offensive possessions with those two players on the court at the same time.
• Def Poss: Number of defensive possessions with those two players on the court at the same time.
• Above / Below Average: A measure of how much better the teammate played when he was on the court with the player, compared to the teammate's average play. This calculates the team's efficiency when these two players were on the court, minus the team's efficiency for all possessions when the teammate was on the court, regardless of who he played with.
