Teammate Impact

The Teammate Impact tool shows how a player’s statistical output shifts depending on which teammates are in or out of the lineup. A star point guard being injured might boost a secondary ball-handler’s assists — or a rim-protecting center sitting out could inflate an opponent’s points in the paint. This tool quantifies those effects.

Note

The app interface is in Spanish. This guide references the actual labels you will see.

Overview

Navigate to “Herramientas” (Tools) in the sidebar and select “Impacto de Companeros” (Teammate Impact). The route is /tools/teammate-impact.

The engine compares a player’s per-game averages in games where a specific teammate played at least 10 minutes versus games where that teammate was absent. The difference reveals how dependent a player’s production is on specific lineup configurations.

How to Use

1. Search for a player — Type into the “Jugador” (Player) autocomplete search field and select a player from the dropdown.
2. Select a stat category — Use the stat tabs to switch between “Puntos” (Points), “Rebotes” (Rebounds), “Asist.” (Assists), and “Triples” (Threes).
3. Review teammate cards — The page displays a grid of cards, one per teammate who has meaningful with/without data.

Understanding the Results

The page title reads “Diff con/sin companero para {playerName}” and a subtitle explains: “Diferencia en {stat} del jugador cuando el companero juega (min 10 min) vs cuando no.”

Teammate Card Elements

Each card in the grid represents one teammate and contains the following information:

Element	Description
Teammate name	Bold header text showing the teammate’s name
Injury badge	A red “Fuera” badge appears if the teammate is currently injured or out
Diff value	The stat difference — displayed in green with a + prefix when positive, red with a - prefix when negative
Stat unit	Label indicating which stat is being measured
Breakdown	Format: “con {avg} · sin {avg}” — shows the player’s average with and without this teammate
Footer	Format: “{N}g con · {N}g sin · {avg} min/g” — game counts and average minutes per game

Reading the Diff Value

A positive diff value (green, +) means the player averages more of that stat when the teammate is on the court. A negative diff value (red, -) means the player averages less when the teammate plays.

For example, if LeBron James shows +3.2 points with Anthony Davis, it means LeBron averages 3.2 more points per game when Davis plays compared to when Davis is out.

Tip

Cards with a red “Fuera” badge are especially important. If a key teammate is currently injured, the with/without data tells you exactly how much that absence has historically affected the player’s output in the stat you are evaluating.

Tips

Tip

Focus on teammates with large sample sizes. The footer shows game counts — a +5.0 diff based on 3 games without the teammate is noise, while +2.5 based on 15 games is a pattern.

Tip

Combine this data with injury reports. If a teammate who normally boosts the player’s stats is listed as out tonight, that is a signal to be cautious on over picks for that stat.

The Teammate Impact tool overlaps with the teammates section on the Player Research page. The research page shows the same with/without data in the context of a full player profile, while this standalone tool focuses exclusively on teammate effects with the stat tab switcher.
