MMQB Fantasy League Archive
A private archive of nineteen seasons of fantasy football.
About
Ten managers have played in the same Yahoo fantasy football league, continuously, since 2007. Nineteen seasons later, the same names still show up on draft night.
Every draft, every trade, every matchup, and every final standing is recorded in Yahoo. But it sits locked inside a season-by-season interface that was never built to be read as history.
This project makes that history readable and searchable for the people who lived it — the league's own members.
What we're building
- All-time record book and head-to-head matrix
- Draft-pick value analysis across two decades
- Career pages for each manager
- Searchable archive of every trade
- Natural-language querying of league history
How it works
Data is pulled from the Yahoo Fantasy Sports API on a nightly incremental schedule into a local datastore and served from cache. Natural-language querying passes cached league data to a commercial LLM API as request context only — no league data is used to train models, and nothing is retained by the provider once a question has been answered.
