Los Angeles Chargers vs Seattle Seahawks — Win Probability

Seattle Beats LAC as Expected; Model Nails Both Margin and Winner

Seattle's 30-23 win over Los Angeles on Sunday played out almost exactly as the model projected before kickoff. The Seahawks were favored at the market spread of 7 points, and the pregame simulation gave them a 70% win probability with an expected final score of 24.8 to 17.7—a margin of precisely 7 points.

The actual result: Seattle won by 7, final score 30-23. The margin matched the projection exactly. The actual scores ran higher than expected—both teams exceeded their modeled output—but the gap between them remained unchanged. Seattle outscored its projection by 5.2 points while Los Angeles exceeded its own by 5.3 points, a near-perfect offset that left the differential intact.

This is a decisive validation of the model's read on the matchup. It correctly identified Seattle as the superior team, assigned them the right degree of edge, and forecast the outcome with precision. The 70% win probability for the favorite proved well-calibrated; the Seahawks won as the chalk, without drama.

For context: the model's expected margin of 7 and the actual margin of 7 represent zero error in the primary metric. The directional call was correct. The confidence level assigned to Seattle was vindicated.

Los Angeles falls to 0-4 after the loss. Seattle improves to 3-1. Neither result reshapes the competitive landscape beyond what was already embedded in the pregame projection—the model saw Seattle as the better team by a touchdown, and that's how it played.

When a projection this precise comes in, it typically reflects either strong underlying data about the teams or a matchup without major surprise variables. In this case, the Seahawks simply performed to expectation and won the game the model said they would.
