Fantasy-Point Arc Comparables

The top-10 most similar long-arc NFL players matched by fantasy-point production curve at this career stage. Each comp's "Peak 3yr fp/g" is their best 3-season fp/g average under Superflex PPR (era-pace-adjusted to modern). Similarity is bounded in (0, 1] — 1.0 means an identical career-stage profile vector. "Career" notes the comp's NFL longevity; the washed out badge flags comps whose career ended by age 30 with fewer than 8 NFL seasons (the engine’s bust definition). The ⏳ 1985 badge marks comps whose snapshot season predates 1999 — the corpus now spans 1980-2025, so Payton, Emmitt, Marcus Allen, Rice, Marino-era greats are eligible matches. Pre-1999 comps carry a 0.9× confidence haircut because era-pace adjustment is principled but not perfect.

How this number is built

Every component below is sourced from the engine output (engine_rankings.json) and the displayed comp table. The final production score is 1,606.

StepValueWhat it is
Comp-weighted projection (v3.3 primary) 1,322 Σ (simi × post-age-fpi) / Σ simi. Sanity check from the top-20 row data on this page: 1,378. This is the “weighted average of the comparable players’ actual realised post-age fantasy points” — Phil's 2026-05-28 brief.
Peak-anchored projection 2,009 The player's own peak-3yr-fp/g × expected games × horizon × 5%/yr time discount, capped at 1.25× the top single-comp projection. Used as a soft blend for elite-tier producers (60/40 comp-weighted / capped peak) so a Mahomes / Allen isn't fully dragged to the comp-pool mean.
Banked-credit floor (diagnostic only) 2,589 The v3.1 “dynasty equity” floor = career_total_fp × yrs-rem-weight + recent rate × short forward window. v3.3 no longer lets this override the projection — banked production is already realised, not “remaining.” Shown for transparency.
Raw projection (pre-penalty) 1,821 Blended comp-weighted + capped peak-anchored, per the v3.3 methodology described above.
× Survival 0.882 Multiplier reflecting how many comps washed out by age 30. Today: 1 − 0.5 × bust_rate.

× Late-breakout penalty 1.000 QB-only. Scales by confidence so unproven late-breakout rookies only pay a fraction of the discount.
× Missed-season penalty (v3.3) 1.000 Multiplicative haircut for players who didn't play (or only played a partial slate) in the most recent NFL season. 0.70 for a full missed season, 0.85 for <8 games, 0.45 for two+ full missed seasons. played full most-recent season
