The ESF model

What drives the number

ESF's forecast uses one input per team, its CAP win pct entering the game, plus an allowance for home field.

Home team's chance when both teams are at the league average (0.50). The rest over 50% is home field.

logit(home win) = 0.143 + 1.649 × home CAP win pct − 1.430 × away CAP win pct

A logistic regression fit on 2010–2025 regular-season games (3,906 games), refit before each season.

How to read this page

CAP win pct. A fading average of game scores with a half-life of 7 of the team's own games. A win scores 1 plus the opponent's win pct; a loss scores the opponent's win pct minus 1. Last season carries in. League average is 0.50; higher is better.

CAP yards per attempt. Yards per play relative to what the down, distance, field position and the specific opponent would predict. Offense: higher is better. Defense (yards allowed): lower is better.

ESF win probability. A logistic regression on both teams' pre-game CAP win pct, with an intercept for home field.

Market. The median of the US books' win probabilities after removing the bookmaker's margin (the vig), from The Odds API. The spread is the most common line across books.
