Muffed answers NFL questions with figures that have already been checked. Every number comes from a gated panel built on nflverse play-by-play, NFL Next Gen Stats and FTN charting data, and every response carries its own source, the date it was verified, and the attribution the data licence requires.
Ask what the data says is actually real in the NFL right now, look up a player's or team's season figures, pull a leaderboard, get a plain explanation of an advanced metric like EPA or CPOE, compare two players side by side, or check a statistic you saw somewhere else — Muffed will tell you the real value when it disagrees. You can also connect a Sleeper league by id to get verified context on the players in it.
Muffed publishes no projections, no start/sit or lineup advice, no draft grades, no rankings-as-advice and no picks, and carries no betting lines or odds. No tool on this server can produce one: there is no projection model behind it and no ranking-as-advice surface.
Every response marks its own boundary. A citation names exactly which figures it covers and states that it does not extend to analysis derived from them. Figures computed on request rather than drawn from the pre-verified panel are labelled `computed_not_verified` and carry the executed method and population size. Where Muffed holds nothing for a request, it says so explicitly, states the coverage it does have, and declines attribution for whatever fills the gap. An assistant calling this server may add commentary, comparison or recommendation of its own on top of the returned figures; that commentary is the assistant's and is outside what Muffed verifies or attributes.
Free, read-only, no account required. Fantasy scoring figures use half-PPR, the most common single redraft default, and say so wherever they appear.

How to quote Muffed's verified NFL figures correctly. Use whenever a Muffed tool returns data — query_stat_leaders, get_entity_metrics, compare_entities, get_metric_definition, list_metrics, verify_claim, get_backfield, run_stat_query, or any sleeper_* tool — or when answering an NFL or fantasy-football question using Muffed figures. Covers quoting the pre-formed sentence, the difference between verified and computed figures, carrying attribution verbatim, honouring disclosures and season coverage, and the no-advice boundary.
Things to ask
- “What does Muffed say is actually real in the NFL right now?”
