Player Grades

What are gradient Player Grades?

Our team of industry veterans and experts evaluates every player on every event that takes place during a game, providing analysis and insights with unmatched attention to detail.

Each event is graded on a scale from -2 to +2 in increments of 0.5, with 0 representing a player performing their role at an expected level. The +/- grades are then converted to a 0-100 scale at the game and season levels, allowing for easy comparison of players across different leagues and positions, relative to their peers.

Player Performance Grades Built in Collaboration with the Premier League's Top Teams

Gradient’s Player Grades were built in close collaboration with some of the Premier League’s most forward-thinking clubs, ensuring the system reflects the demands of elite football environments. These teams played a critical role in shaping how we define and evaluate on-pitch decision-making, effort, and execution. By working hand-in-hand with performance analysts, coaches, and recruitment leads at the highest level, we’ve developed a grading framework that’s objective, consistent, and deeply aligned with the realities of professional football.

Our Grading Process

Unlike traditional data, Gradient measures performance relative to expectation instead of just traits or measurable factors. The system looks at every event, creating a large sample size that eliminates bias and indentifies undervalued players while avoiding player hype. The grading process evaluates players objectively, regardless of perceived ability.

Gradient's grading process is built on a strict grading guide to turn subjective analysis into objective measurements.

Play-by-Play Grading

We grade every event on a -2 to +2 scale based on performance relative to expectation, using strict training, rigorous checks, and multiple reviewers to ensure objectivity, accuracy, and consistency.

Normalizing the Grades

We then adjust raw grades using models that factor in game context, accounting for over 135 data points per play. This ensures more accurate, nuanced evaluations by comparing performance to expected outcomes.

Converting the Grades

Finally, we convert the raw player grades using statistical models that factor in game context and over 135 data fields per play. This ensures grades reflect performance relative to expectations, providing more accurate and nuanced evaluations across key facets like passing, shooting, and defending.

Grades Versus Stats

We grade each action based on quality, not just the outcome. For example, if a midfielder plays a poor through ball that ends in interception, they’ll be marked down even if the opponent miscontrols the pass and your team regains possession.

No amount of dribbling or second‑chance assist will hide a bad pass. Traditional stats like key passes or assists can be misleading. The same applies to defenders: a centre‑back who concedes few goals thanks to great saves may still earn a low grade if they lose too many duels or are out of position.
