Sources & Methodology

Last reviewed: August 14, 2026

Coverage statement: the directory is broad from 1974 through 2026 and selective before 1974. Early professional football records are incomplete, so this archive does not claim to be a census of every historical player.

Primary datasets

Structured player and team records are imported from the open nflverse player and team datasets. Editorial career pages link to the relevant Pro Football Reference record. Selected early-era and historically significant profiles are curated separately so incomplete modern feeds do not overwrite better historical dates or biographical detail.

Record merging

Records are matched by normalized player name and stable identifiers where available. Curated historical fields take precedence for career span and researched biography; source headshots, identifiers and college fields are retained when the curated record does not supply them. Duplicate franchise identities are consolidated before display.

Stories

The 100 career stories are data-informed editorial profiles. Each uses the named player's documented career span, position, college, draft and final recorded team when available. The prose provides historical interpretation, not a game-by-game statistical encyclopedia. A direct career-source link accompanies every story.

Photographs and rights

Images are reference photographs loaded from linked source records. Copyright and reuse rights remain with the respective owners or licensors. An available image is not presented as public-domain material.

Known limitations

Corrections

Potential errors are reviewed against the linked record and at least one additional authoritative source when practical. A public corrections address will be added here when the official Google Play developer listing is activated.
