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.

Box score yards per attempt. Yards divided by attempts, counted the way an official box score counts them: rushing includes scrambles and kneel-downs; passing is gross yards per pass attempt, sacks excluded.

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.
