Reached 1% of the all-time Sacks leader — a rotational/depth all-time profile at the position.
A 0–100 scale where 100 = matched the all-time leaderat this position. Built only from visible encyclopedia data — career production vs. the all-time leader, plus efficiency (EPA) and comparable-player confidence — so it's a transparent context score, not a subjective rating. Tiers: Elite ≥ 85 · Strong ≥ 65 · Solid ≥ 45 · Depth < 45. Comparable-player confidence: 90%.
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+).
College stats are not imported for this profile yet.
StatVault has the verified college attribution (Delaware), 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.
Statistical + physical similarity across every player in the database, position-relevant (0–100%).
