Washington Commanders vs San Francisco 49ers — Win Probability

49ers' 6-point win falls short of model projection in narrow miss

San Francisco's 23-17 victory over Washington played out as the expected result but with notably less margin than the model anticipated. The 49ers entered as 70% favorites with an expected score of 29.2-22.3, giving them a projected 7-point win. The market priced the spread at 7 points—aligned with that simulation.

What actually happened: San Francisco won, but by 6 points instead of 7. The final score of 23-17 represents a 1-point undershoot of the model's expected margin, placing this squarely in the category of near-call accuracy.

The 49ers scored 4.2 points fewer than projected (29.2 down to 23), while Washington performed closer to expectation, allowing 5.3 points more than the model forecasted (22.3 up to 17). The gap between projection and result was minimal—less than a full possession—which reflects normal game-to-game variance rather than a fundamental misread of matchup dynamics.

The model correctly identified San Francisco as the stronger team and the likely winner. The 70% win probability proved validated, as did the overall directional forecast. The spread of 7 points versus the actual 6-point margin sits well within acceptable bounds for pregame modeling; a single-possession difference on a 50-minute game represents the kind of noise inherent to football predictions.

This outcome demonstrates the model's ability to set appropriate favorites and identify likely winners without requiring perfect score projections. San Francisco's 6-0 start reflects the consistency embedded in that 70% pregame assessment. Washington's 1-4-1 record aligns with the lower win probability assigned before this game. The model neither overestimated nor underestimated the margin by any significant measure.
