PFF in football usually refers to Pro Football Focus, a data and analytics company that grades every player on every play to produce advanced stats and player grades. What PFF means in football

• Pro Football Focus (PFF): A analytics firm that watches games, grades each player's performance on every play, and produces 0–100 grades plus a suite of advanced stats. Their grading emphasizes performance relative to expectations for a given task, rather than just traditional box-score results.

• Grades scale and interpretation: PFF assigns events a value on a scale that typically ranges from around -2 to +2 per event, with 0 representing expected performance and larger positive or negative numbers indicating better or worse-than-expected outcomes. These grades feed into player and team evaluations, drafts, and game analyses.

• Common usage in broadcasts and analysis: PFF data is used to discuss player quality, rankings, and WAR-like value estimates; fans and media often refer to PFF grades or rankings to gauge how well a player performed relative to peers.

• How it differs from traditional stats: Unlike traditional stats that tally outcomes (yards, catches, tackles), PFF aims to measure execution on each play against the task required by the position, attempting to isolate performance quality from context and hype.

• Practical applications: Teams use PFF data for player evaluation, contract discussions, and game planning; media outlets cite PFF grades to illustrate strengths and weaknesses of players.
