Career Value · Proprietary
KV-H asks how good a career was. VORP asks how much value it produced — by adding up every season’s quality above a freely-available replacement player at the same position. Longevity counts: a long run of above-replacement seasons outscores a short peak.
Method
VORP = Σ max(0, season KC-H − positional replacement level). Replacement = the 30th percentile of season scores in the position group. Rewards sustained above-replacement play (quality margin × longevity) — the career-value lens kvScore caps.
Replacement levels (KC-H): Edge 51 · RB 50 · LB 47 · S 48 · TE 46 · WR 48 · QB 36 · DL 47 · CB 49. 4,695 players with ≥3 scored seasons.
