Brock Purdy is a career quality starter — a quarterback whose body of work places Purdy in the top quarter of all players at the position historically. The Knox model values sustained contribution over flash, and Purdy's career arc reflects exactly that kind of reliable professional-grade performance.

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.

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

Brock inherited the San Francisco 49ers QB room from Jimmy Garoppolo (2017–2022), and holds it as the most recent the corpus records.

Steve Bono 1989–1993Elvis Grbac 1994–1996Jeff Garcia 1999–2003Tim Rattay 2000–2005Alex Smith 2005–2012Colin Kaepernick 2011–2016Jimmy Garoppolo 2017–2022Brock Purdy 2022–2025

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.
