Washington Commanders vs Philadelphia Eagles — Win Probability

Model's 5.4-Point Edge Proved Accurate as Philadelphia Edges Washington

Philadelphia's 24-22 victory over Washington validated the pregame model projection, though the actual margin of victory fell short of the forecast by 3.4 points.

The model projected a Philadelphia win with a 66% probability entering the game, aligned closely with the market's 5.5-point spread favoring the Eagles. Philadelphia's expected score of 25 compared to Washington's 19.5 created a forecast margin of 5.4 points—almost exactly matching the betting line's assessment of the matchup.

What actually happened fell in line with the model's directional read but undershooted the projected point differential. Philadelphia won as expected, but by only 2 points rather than the forecasted 5.4. The Eagles scored one point below their simulation (24 vs. 25), while Washington exceeded expectations significantly, putting up 22 instead of the projected 19.5—a 2.5-point outperformance for the losing team.

This outcome represents neither a model failure nor a major surprise. The model correctly identified Philadelphia as the superior team with roughly two-to-one odds on victory, and the Eagles delivered that result. The gap between the 5.4-point projection and the 2-point actual margin—3.4 points—falls within a reasonable range for single-game variance in football. The projected winner won by a smaller margin than simulated, but the fundamental read on team quality and game direction proved sound.

The margin compression came primarily from Washington's offense exceeding its model expectation rather than Philadelphia underperforming. This tighter-than-projected outcome doesn't signal a fundamental model miscalibration; it reflects the inherent volatility of weekly NFL results. The Eagles' victory confirms the pregame assessment held up under the week's actual conditions.
