Proprietary StatVault Metrics
College stats are not imported for this profile yet.
StatVault has the verified college attribution (NW Missouri State University; Los Medanos College), 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.
Dave inherited the New York Giants DL room from Barry Cofield (2006–2015), and handed it to Linval Joseph (2010–2013).
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.
Statistical + physical similarity across every player in the database, position-relevant (0–100%).
