What it measures

The GRID (Gridiron Ratings IDentifier) system provides a single source of truth for player identity across the platform. Each player receives a unique UUID-based identifier displayed as GRID-{8char}.

Inputs

• Player name: Full legal name used as the primary matching key.
• Team assignment: Current NFL team, updated when players change teams.
• External ID mappings: Cross-references to Sleeper, ESPN, PFR, and other platform identifiers.

Scale

• GRID-{8char}: Unique 8-character identifier derived from the player's UUID, displayed on player cards and profiles.

How to use it

• Use GRID IDs to cross-reference players across rankings, news, depth charts, and projections.
• When a player changes teams, their GRID ID stays the same - all platform features update automatically.
• GRID IDs appear on player card fronts (top-left badge) and backs (header) for easy identification.

Limitations

• GRID IDs are not a performance metric - they serve as infrastructure for data integrity.
• Name matching for auto-linking may miss players with unusual name spellings or recent name changes.
• External ID mappings depend on third-party data sources which may have gaps or delays.
