Understanding These Stats

Defense

Tkl / Solo / Ast — Combined tackles (Solo + ½ Assist). Solo = unassisted. Ast = helped by a teammate.

TFL — Tackles for loss — stops made behind the line of scrimmage (run stuffs + QB contain).

QBHits — QB hits — any legal contact on the quarterback, including but beyond sacks (hurries that land).

Sk — Sacks — tackled the QB behind the line for a loss. Half-sacks shared between defenders.

Dis — Disruption plays = sacks + QB hits + TFL. The composite pass-rush / run-stop impact stat for one season. Elite pass rushers post 30+ disruption plays per season.

Int — Interceptions caught by this defender.

PD — Passes defended — deflections and breakups.

FF / FR — Forced fumbles (stripped or jarred loose). Fumble Recoveries.

TD — Defensive touchdowns — picks, fumble returns, safeties returned.

Sfty — Safeties — tackled the ball carrier in their own end zone.

Snap Counts (2012–present)

Off / Off% — Offensive snaps played and share of team total. The most reliable usage metric for skill positions and OL.

Def / Def% — Defensive snaps played and share of team total.

ST / ST% — Special-teams snaps played and share of team total.

Proprietary StatVault Metrics

KV-H (Knox Value-Historical) — Era-normalized career rating 0–100 within position group, calibrated so a 50 = average starter and 90+ = all-time great. Covers 1999–present. Built on a 5-year IQR/robust-std era window.

SIS (Snap Impact Score) — Per-snap production z-scored within position group and era (2012+). Measures how much a player produced per opportunity, not raw volume.

VORP (Value Over Replacement) — Sum of max(0, season KV-H − positional replacement level) across a career. Measures career value above the minimum-roster baseline at each position.

Durability IQ — 0–100 score reflecting how many games a player played relative to peers at the same position in the same era. Adjusts for injury-shortened seasons.
