RosterSim

Pick a 2025 franchise (schedule + real defense), a 2025 head coach (play-calling tendencies), and an offensive roster of 2025 players — then run a deterministic Monte Carlo season simulation.

3. Simulation Settings

Notes & limitations:
  • Season basis: 2025 (real schedule, real coach tendencies, real player profiles — v1 has no historical players or coaches).
  • Standings tiebreakers use win% → head-to-head → division record → conference record → points-for → seeded-random; common-games and strength-of-victory/schedule steps are intentionally omitted (approximation, not the full NFL tiebreaker procedure).
  • Playoff-round player stats use a league-average opponent multiplier and a synthetic win/loss game-script signal rather than a modeled margin (the regular season uses the real simulated margin and real opponent).
  • Selected players are duplicated onto their real 2025 teams' ratings — the other 31 teams are not depleted.
