NBA data & analytics tools
Every NBA player, graded across 700+ metrics.
Leaderboards, shot charts, lineup modeling, player report cards, and other data and tools used by basketball writers and podcasters, team broadcasts, and the team and agent communities. Start with the free tools, then unlock everything for $5 a month.
Every category we grade, sorted four ways:
Skill 12
Impact 2
Productivity 2
Context 12
Most basketball data stops at what happened. We live in the details that define these three elements, and in the relationships between them. That is our purpose.
Impact
LEBRON
Our flagship impact metric
Estimate using a
Box prior
Regularized
ON-off
LEBRON accounts for a player’s role, the specific teammate and opponent combinations they actually faced, and adjusts for outcomes driven by variance, so what you are reading is true impact rather than noise.
LEBRON is a measure of impact per 100 possessions. O-LEBRON is the offensive component. D-LEBRON for defense.
LEBRON Wins Above Replacement (LEBRON WAR) is a measure of aggregate impact, meaning minutes matter.
Talent
Talent Metrics
Production and impact depend heavily on situation. Our talent metrics are built to be independent of situation, so they travel with a player from role to role and team to team. They measure not just what a player did, but who they are.
Talent
Overall Talent & Optimization
We roll up key talent metrics to forecast expected player impact given their skills, physical tools, usage and job. That evaluates a player directly instead of inferring who they are from plus minus data.
Comparing that forecast against actual impact is what we call Optimization: a way to surface overrated players, find under the radar names ready for a breakout, and evaluate coaches, enabling smarter analysis of player movement and team context.
Context
Offensive & Defensive Roles
Positions are a relic. Our Offensive Role and Defensive Role designations capture the real distribution of labor on a basketball court, which makes every comparison built on top of them a fairer one.
Offensive Roles introduction →Defensive Roles introduction →
Context
Teammate Context
Who you play with changes the spacing on your isolation, the openness on your corner three, and the help behind you on the back line. We measure what a player is working with, which is how you tell a stud from someone along for the ride on a group project.
Context
Deep Matchup Analysis
Your efficiency as a scorer or a stopper depends heavily on who you are guarding, and who is guarding you. Matchup data that accounts for switching and helping cuts through the blur and gives a clear view of each player.
