Understanding These Stats

Rushing

Att — Rushing attempts (carries).

Yds — Rushing yards.

TD — Rushing touchdowns.

Y/A — Yards per carry — rushing yards ÷ carries. The core rushing efficiency rate; 4.5+ is solid, 5+ is elite.

TD% — Touchdown rate per carry (TDs ÷ carries × 100) — measures scoring efficiency per touch independent of volume. Red-zone workhorses lead here.

1D — First downs gained on rushing plays.

1D% — First-down conversion rate (first downs ÷ carries × 100) — how often a carry moves the chains. Top RBs convert on 25%+ of attempts.

Fmb — Rushing fumbles lost — the key ball-security stat for running backs. Below 1 per season is elite.

Receiving

Tgt — Targets — how many times the receiver was thrown to, regardless of completion.

Rec — Receptions — catches made.

Yds — Receiving yards.

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.
