The Challenge

Fantasy football leagues build a decade of memories — trophies, sackos, blowouts, dynasties — but ESPN buries it all behind paginated season views nobody actually clicks through. The history of a long-running league deserves a museum, not a dropdown. The hard part: that history lives in an API designed for the current season, not for archaeology.

What I Built

Plug in your ESPN league and MMT HQ pulls every season back to year one — every champ, every sacko, every blowout, every receipt — and turns it into a permanent fantasy football museum. Six themed exhibit wings, on-air broadcast styling, and lifetime exhibits that update automatically as new seasons close.

Architecture Decisions

The full league history is ingested once and treated as a permanent archive, so the museum stays up even when ESPN's API is slow, changes shape, or drops old seasons. Exhibits are computed from the archive rather than hand-curated — records like 'biggest blowout ever' stay correct forever without maintenance. The broadcast-style presentation was a deliberate bet that fantasy history should feel like SportsCenter, not a spreadsheet.

What I'd Do Differently

Normalize team ownership across seasons from the start — league members change team names yearly, and stitching a decade of identities together after the fact was the messiest part of the build. Identity resolution should have been the first system, not a patch.

The Result

The museum your league deserves: open Sundays, records stay open forever. Shipped under Checkmate Labs, and the studio's deepest data product — an argument that the best fantasy content is the history your league already wrote.
