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.

Franchise Succession

the room, before and after

Alphonse opened the New York Giants RB lineage the corpus knows, and handed it to Frank Gifford (1952–1964).

Alphonse Leemans 1936–1943Frank Gifford 1952–1964Joe Morris 1982–1988Dave Meggett 1989–1994Rodney Hampton 1990–1997Tiki Barber 1997–2006Brandon Jacobs 2005–2013Saquon Barkley 2018–2023

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.
