How each offense played

Box score and CAP yards per attempt for each offense. Higher is better for an offense; a CAP value above zero means the offense beat what the situation and this defense would predict.

Sacks (raw counts):SEA sacked 1 time · ARI sacked 2 times. Sacks are counted, not CAP-modeled.

Box score yards per attempt count yards as an official box score does: rushing includes scrambles and kneel-downs; passing is gross yards per pass attempt, sacks excluded. CAP yards per attempt measure each play against what the down, distance, field position and this specific defense would predict; above zero means the offense beat that expectation.

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.
