New Orleans Saints vs Baltimore Ravens — Win Probability

Saints' 24-17 Upset Over Ravens Exposes Major Model Miss

New Orleans pulled off a 24-17 road upset over Baltimore on Sunday, a result that deviated sharply from both the pregame projection and market consensus.

The model had given the Saints only a 25% win probability before kickoff, expecting them to lose by 9.1 points (projected score: 18.8–27.8). The market was even more bullish on Baltimore, installing the Ravens as 9-point favorites. Both readings ranked Baltimore decisively ahead.

What actually happened was a 7-point Saints victory—a 16.1-point swing from the model's expected margin. The Saints outscored their projection by 5.2 points while holding Baltimore 10.8 points below what the model forecast. That gap is large enough to signal a material misread on either team's ability to execute in this matchup.

The upset was genuine. The Saints came in as decided underdogs and delivered a complete reversal of the expected outcome. New Orleans moved to 1-1 with the win; Baltimore fell to the same record despite being favored by two possessions' worth of points.

For the model, this was not a close miss—it wasn't a case of picking the right winner by the wrong margin, or nearly getting the spread right. The projection missed the outcome entirely while also underestimating New Orleans' scoring and overestimating Baltimore's. Neither the 25% win probability nor the 9-point expected deficit left room for a Saints win of this magnitude.

The market's 9-point line landed closer to the actual result than the model's 9.1-point expectation, but both were fundamentally wrong about which team would win. For a brand built on factual accuracy, this game represents a clear failure to identify Saints value where it existed.
