Justin Herbert packed more value into his peak seasons than almost any quarterback in NFL history — a comet career that burned brightest when it mattered most. His KV-H peak of 75 is historically rare; while longevity was not his calling card, the impact of his best seasons is undeniable.

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.

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.

Franchise Succession

the room, before and after

Justin inherited the Los Angeles Chargers QB room from Philip Rivers (2004–2019), and holds it as the most recent the corpus records.

Ed Luther 1980–1984Stan Humphries 1992–1997Drew Brees 2001–2005Philip Rivers 2004–2019Justin Herbert 2020–2025

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.
