Where this data comes from
Modern-era stats (1999+) come from nflverse's open data releases. Pre-1999 seasons are backfilled additively from Wikipedia and NFL.com's own official season pages — never from rights-restricted sources.
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.

Era Translator
Rec Yds translated to the 2025 NFL — each season's standing among its own-era peers, projected onto 2025's scoring environment. Modern-era (1999+) coverage.
Pre-1999 players have bio + draft data but counting stats are not available from any freely-licensed source. Players with ★ Career Only see verified career aggregates from nflverse draft_picks.
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.
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.
