Philadelphia Eagles vs Jacksonville Jaguars — Win Probability

JAX holds off PHI in close call model saw coming from distance

Jacksonville's 19-17 win over Philadelphia played out almost exactly as the model feared: tighter than expected, but in the direction the model predicted.

Before kickoff, the model projected Jacksonville to score 24.5 points and Philadelphia 17, yielding a 7.5-point Jacksonville advantage. The market agreed, installing JAX as a 7.5-point favorite. The model gave Jacksonville a 71% win probability, a comfortable but not dominant lean.

What actually happened was far closer. Jacksonville won 19-17—a 2-point margin instead of the projected 7.5. That's a 5.5-point miss on the expected spread.

The gap reveals useful detail. Jacksonville underperformed its projection by 5.5 points (24.5 to 19), while Philadelphia exactly matched it (17 to 17). The Jaguars' offensive execution fell short of what the model's inputs suggested it should produce. Yet Jacksonville still won, and the model got the winner right, which matters more than the margin in a binary outcome.

This was not an upset—Jacksonville was favored and won—but it was a closer contest than the model's pregame simulation indicated. The 2-point actual margin versus the 7.5-point projection is a meaningful underestimation of Philadelphia's ability to stay competitive. The Eagles scored exactly what the model expected; Jacksonville simply didn't deliver the offensive output the projection implied.

Jacksonville improves to 4-1. Philadelphia falls to 2-3. The model called the winner correctly at 71% confidence, but the tighter result suggests Jacksonville's margin of victory was compressed by factors the pregame projection didn't fully capture—whether execution, game flow, or roster performance in the specific matchup.
