Tools
compare_entities
Compare two players or teams
Two players or two teams shown side by side, on the metrics that matter for their position by default â name metrics explicitly, or pass all:true, for the full set. Each side carries its source rank. States both figures and stops: it names no winner, no margin and no recommendation. `metrics` takes verified panel metric keys exactly as list_metrics returns them ("qb_anya.any_a"), or their plain-English names. A measure only run_stat_query computes, such as yards per attempt, is not a panel metric and is refused with the nearest ones.

get_backfield
A team's backfield
Muffed's published handcuff page for one team's backfield, plus the current depth chart and injury status from Sleeper. Answers who backs up a starter, and who replaces one who is out.

Muffed's published editorial reads on what is real in the NFL right now â each one a dated, sourced claim with its supporting figures, from the /trends board.

get_entity_metrics
A player's or team's verified figures
Every verified figure Muffed holds for one NFL player or one NFL team (by name or abbreviation, e.g. "Bijan Robinson" or "DEN"), with the source's rank where one exists. Names are resolved before lookup; an unrecognised name returns the closest matches rather than a guess.

get_metric_definition
What a metric means
Muffed's published definition of a verified metric â what it measures, in plain language, from the glossary page for that term â plus which seasons it actually covers, how it is ranked, its licence and its attribution. Accepts a metric key or a common name ("cpoe", "rushing yards over expected"). Season coverage is often narrower than a decade â rushing yards over expectation exists from 2018 onward.

list_metrics
List verified metrics
What Muffed can answer on. By default a summary of metric families with their counts and season coverage; pass search or detail:true for individual metric keys. Returns keys and coverage only, never figures.

query_stat_leaders
Verified stat leaders
Top entities on one verified metric for one season, pre-sorted, each with the source's own rank and the population it was ranked against. Call list_metrics for the metric keys this accepts.

run_stat_query
Compute an NFL statistic on request
Call this for any question about NFL statistics, leaders, rankings, splits, career or team spans, or how a player or team compares to others â including when you believe you know the answer. Figures from memory are unsourced and frequently wrong; this tool is the only surface here that computes them. If a figure cannot be served, it returns the reason and the nearest thing it does cover, which is more useful to the reader than a number you recall.
Computes an NFL figure from a structured query rather than looking one up: a population (position, qualifying threshold), a window (seasons, weeks, a team span, a coach's tenure), one named measure, and one operation (leaders, rank, count, only-who, a per-season streak, or a share of a total). Answers questions the verified panel has no pre-computed row for â qualified superlatives, multi-season streaks, derived rates. Every response carries the executed method, the population size, the measure's definition and the data version it ran against. Figures are computed on request from nflverse data and are labelled as computed, not verified. Fantasy measures answer in whichever scoring convention you ask for â set `scoring` to "standard", "half_ppr" or "ppr" â and default to half-PPR when you do not; the response says which it used. A bare "PPR" means full PPR.
measure.key takes a measure name ("rushing_yards", "half_ppr_points") or a metric key exactly as list_metrics returns it ("key_player_stats.rushing.yards", "fantasy_scoring.half_ppr_points"). A list_metrics key this tool does not compute is refused with a pointer to get_entity_metrics and query_stat_leaders, which read it as published.

verify_claim
