Different fantasy-football data sources serve different purposes. A fictional practice pool allows testing drafts without representing real athletes. Delayed real NFL statistics support historical analysis and later scoring updates. Real-time projections and play-by-play require a suitable vendor connection.
Fictional practice players
Mock draft names and example scores are synthetic. They must not be presented as NFL results. Practice leagues are useful for learning player queues, draft order and the interface.
Delayed nflverse data
The current catalog includes real NFL player identities and weekly published open statistics attributed to nflverse contributors under CC BY 4.0. The import schedule and most recent week are displayed on Data Health.
Historical-form estimates
Research combines the last three recorded games with the season average, and it reports limited-sample warnings. It does not model future injuries, game roles, opponents, weather or winning probabilities.
Commercial sports data
Licensed NFL data is connected for ranked players, ADP, projections and periodically imported weekly fantasy statistics. Real-player commissioners may opt into GOAT scoring; gameweek totals remain provisional until the results are verified and settled. This is not a guarantee of continuous real-time play-by-play scoring.
How to verify freshness
Visit Data Health and inspect the latest imported season, week, timestamps and connection status. GOAT scoring is opt-in per league, and automatically prepared next-week lineups can be reviewed or manually replaced before kickoff. When a league week has no statistics, the matchup center should say it is awaiting data, not show a misleading final 0–0.
