Post-Game Analysis

How our model performed

The Seahawks defeated the 49ers 13-3.

Our model predicted the Seahawks would win with 54% confidence -- and they delivered. A close call, but the model's slight lean proved correct.

Looking at the factors our model weighed:

  • Recent Form favored the Seahawks and was a contributing factor: Seattle Seahawks (12-6) in better form than San Francisco 49ers (9-9)
  • Defensive Efficiency favored the Seahawks and was a contributing factor: Seattle Seahawks defense (4.7 YPP allowed) is stronger than San Francisco 49ers (5.1 YPP allowed)
  • Home Field Advantage favored the 49ers and was a contributing factor: San Francisco 49ers are 5-6 at home this season (divisional game, reduced advantage)

This analysis was generated from our model's pre-game assessment compared against the actual result. Factor accuracy helps improve future predictions.
