StatVault aggregates multiple open-licensed and proprietary sources into a single profile. The depth indicator above shows which layers are available for this player.
Pre-1999 players have bio + draft data but counting stats are not available from any freely-licensed source. Players with ★ Career Only see verified career aggregates from nflverse draft_picks.
Production per snap — the box score normalized by opportunity. SIS is z-scored within defensive backs, shrinkage-regularized so small samples don't spike, over the NFL snap-count era (2012+).

Proprietary StatVault Metrics
College stats are not imported for this profile yet.
StatVault has the verified college attribution (Belhaven College; Minnesota; Mississippi Gulf Coast CC), but no parsed college box-score table is present in this profile artifact. The section stays here so every profile has a consistent college-stats landing point without fabricating unavailable rows.
Career teammates and draft class, derived from year-by-year rosters — every name is linked.
Tramaine inherited the San Francisco 49ers DB room from Tarell Brown (2008–2013), and handed it to Carlos Rogers (2011–2013).
The room is reconstructed from arrival order among durable members (≥4 seasons with the club) at the player’s position group — a lineage by arrival, not a week-by-week depth chart. Distinct from the league-wide positional GOAT torch.
