DATA SOURCES

NFL schedules, rosters, injuries, play-by-play and statistics: nflverse, used under CC BY 4.0. SCOUT22 aggregates and transforms the source data; independent S22 calculations are not nflverse endorsements.

US weather: National Weather Service. International forecasts: MET Norway, CC BY 4.0. Units are converted to Fahrenheit and miles per hour. Stadium coordinates: Wikidata (CC0). Forecasts carry timestamps and may change.

Advanced position evidence uses the existing verified licensed source records at their stated cutoff. New automated PFF retrieval requires appropriate licensing. Missing advanced evidence preserves the last verified grade where available.
