This chart is not the model. It shows the inputs that read well as a side-by-side. 7 of the model’s heaviest-weighted inputs have no head-to-head form and are not drawn here: point differential, overall matchup, team win rate, pass matchup among them. The full list of all 55 is on the methodology tab.
Around the game
- SchemeCHI
CHI faces a 4-3 front
DET's roster profiles as a 4-3 base defense.
Base front is inferred from roster composition (agrees with snap data at Spearman 0.50). Most teams play nickel by default, so this is a weak descriptor: measured defensive efficiency carries far more weight in the model.

Over the last 10 games (exponentially weighted), DET has been being outscored by opponents by 0.1 points per game.
- VenueCHI
CHI at home
Home teams have won 54.7% of games in the training window; the model prices this in rather than applying a fixed bonus.
- RestCHI
CHI holds a rest advantage
3 more days of recovery than the opponent.
- Context
Divisional matchup
Familiar opponents; historically tighter margins.
