Preseason rating = last season's SP+ regressed toward the mean, nudged by returning production, recruited talent and recruiting-class strength — the weights LEARNED from 10 seasons by walk-forward, not guessed. Win totals are a Poisson-binomial over the real schedule; game randomness and rating uncertainty are both folded in.
Returning-production and preseason SP+/FPI for 2026 publish in late summer. Until then this regresses 2025 final ratings toward the mean — it will sharpen automatically when those inputs land. Honest by design: every number ships with a range, never false precision.
We tested recruiting-class strength and transfer-portal movement on top of the base (last-year rating + returning production + talent). Recruiting IMPROVED the backtest (8.06→7.90 rating RMSE) and is included; the transfer portal did NOT add signal beyond talent + recruiting (8.07 RMSE) and is honestly left out.

Method: next-season rating is last year's SP+ regressed toward the mean (carryover 62%, learned from 2019+), plus returning production and recruited talent when published. Win totals are a Poisson-binomial over the real 2026 schedule with game randomness and rating uncertainty both folded in — so the range is the believable band of outcomes, not a guarantee. Backtest is strictly walk-forward (fit on prior seasons only). This is a season-level outlook, not a per-game spread. Source: CollegeFootballData (SP+, returning production, talent, schedule).
