Understanding These Stats

Passing

Cmp / Att — Completions and pass attempts.

Cmp% — Completion percentage — completions ÷ attempts × 100.

Yds — Passing yards — total air + yards after catch on completions.

TD / TD% — Passing touchdowns. TD% = TDs per 100 attempts, measuring scoring efficiency.

Int / Int% — Interceptions thrown. Int% = INTs per 100 attempts — the primary ball-security metric.

Y/A — Yards per attempt — passing yards ÷ attempts. The core passing efficiency rate.

AdjY/A — Adjusted yards per attempt: (Pass Yds + 20×TD − 45×INT) ÷ Att. Penalizes turnovers and rewards touchdowns — widely considered the most predictive single-season QB metric.

TD:INT — TD-to-interception ratio — passing touchdowns ÷ interceptions thrown. Elite QBs sustain career ratios above 3.0; HOF greats often exceed 4.0. Not shown when no interceptions.

Rate — NFL passer rating — the official formula combining Cmp%, Y/A, TD%, and INT% on a 0–158.3 scale. Good QB performance ≈ 90+; elite ≈ 110+.

Sk — Times sacked — how many times the QB was brought down behind the line of scrimmage.

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.

TD — Receiving touchdowns.

Ctch% — Catch rate — receptions ÷ targets × 100. Measures how reliably a receiver turns opportunities into gains. 70%+ is elite.

Y/R — Yards per reception — receiving yards ÷ receptions. Measures big-play ability; 15+ is elite for WRs.

Y/Tgt — Yards per target — receiving yards ÷ targets. The single most complete receiving efficiency metric: accounts for both drops and incomplete targets. Elite receivers post 8+ yards per target.

AirYd/T — Air yards per target — average depth of route at time of target. High values indicate a deep threat role; low values indicate a slot/check-down role.

1D — First downs gained on receiving plays.

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.
