What does on/off mean in Explorer?

It compares a team’s offensive, defensive and net rating per 100 possessions with the player on the floor and on the bench, in the same games. Minutes and possessions on both sides are printed, so a small sample is visible.

Net rating is points scored minus points allowed per 100 possessions. A positive number means the team outscored its opponents over those possessions.

Which games and seasons do the NBA advanced stats cover?

The examples on this page use the 2025-26 NBA regular season. On/off uses the games where the lineups rebuilt from play-by-play match every player’s box-score minutes; each answer says how many of the player’s games that is.

Does a good on/off number mean the player caused it?

No. On/off describes what happened with him on and off the floor; his teammates and opponents differ between the two samples. Explorer says so under every on/off answer.

Can Explorer give a lineup rating for two players together?

Not yet. The closest question it answers is a player’s plus-minus per game in the games a teammate also played, for example “Luka Doncic plus-minus with Austin Reaves 2025-26”.

Question patterns

[player] on off [season]
For example: Cooper Flagg on off 2025-26
[team] [offensive, defensive or net] rating with [player] on the floor [season]
For example: Mavericks defensive rating with Cooper Flagg on the floor 2025-26
[team] with and without [player] [season]
For example: Knicks with and without Jalen Brunson 2025-26
[player] usage rate, PIE, net rating or defensive rating [season]
For example: Luka Doncic usage rate 2025-26
[player] true shooting % or effective field goal % [season]
For example: Nikola Jokic true shooting % 2025-26
[player] plus-minus with [teammate] [season]
For example: Jalen Brunson plus-minus with Karl-Anthony Towns 2025-26
NBA teams best defensive rating, or fastest pace [season]
For example: NBA fastest pace 2025-26

Name the season with both years, as in 2025-26. On/off and these ratings are answered for whole seasons, not a last-few-games window, because a handful of games is mostly noise. Say “on off”, “on vs off” or “with [player] on the floor”.

NBA advanced stats

2025-26 regular season

On/off impact

On/off: the team’s ratings with the player on the floor and on the bench, in the same games
Net rating: points scored minus points allowed per 100 possessions
Offensive and defensive rating: points scored and points allowed per 100 possessions (for defense, lower is better)

Games and seasons: 2025-26 regular season, games with play-by-play whose lineups match the box score. Each answer prints the games, minutes and possessions on both sides.

Team ratings and shooting efficiency

True shooting %: points per shooting attempt, counting threes and free throws
Effective FG%: field goal percentage with a made three counted as 1.5 twos

Games and seasons: 2025-26 regular season. Team ratings and shooting are season totals (sum over sum); team boards rank teams with at least 70% of the most games played. A player’s own rating (“Victor Wembanyama defensive rating”) is his team’s rating with him on the floor, averaged over his games weighted by his minutes.

Usage, pace and impact

Usage rate: the share of his team’s possessions a player ends with a shot, a free throw trip or a turnover while on the floor
PIE: Player Impact Estimate: a player’s share of the game’s positive events, such as points, rebounds, assists and steals, less misses, fouls and turnovers
Pace: possessions per game

Games and seasons: 2025-26 regular season. Usage and PIE are minutes-weighted averages of each game’s value from the advanced box score. Pace ranks teams with at least 70% of the most games played.

Two players together

Plus-minus with a teammate: the player’s plus-minus per game, counting only the games the teammate also played

Games and seasons: 2025-26 regular season, games both players appeared in. It is a game-level number: how the pair performs on the floor together as a lineup is not answered yet.

The league’s highest usage rates are on the NBA usage rate leaders page.

Other sports

NFL

Yards per target: receiving yards divided by targets
EPA per play: expected points added: how much each play changed the offense’s expected points, averaged per play (pass-catchers only)

Games and seasons: The 2025 NFL season, computed from the player’s totals. Boards need a minimum number of carries or targets, said in the answer.

College football

Yards per carry: rushing yards divided by carries

Games and seasons: The 2025 season, regular season and postseason, computed from totals. The board needs a minimum number of carries, said in the answer.

College basketball

Offensive rating: points scored per 100 possessions

Games and seasons: The 2025-26 college basketball regular season, computed as sum over sum. Rankings need a minimum number of games, said in the answer.
