Buffalo Bills vs Las Vegas Raiders — Win Probability

Buffalo edges Vegas in tight result; model slightly overestimated margin

Buffalo's 33-30 win over Las Vegas played out closer than the model anticipated, though the pregame projection correctly identified the Bills as the likely winner.

The model projected a Buffalo victory by 5 points, with expected scores of 29.2 for Buffalo and 24.2 for Las Vegas. The market agreed on Buffalo as the favorite, posting a 5-point spread that aligned perfectly with the simulation. Buffalo carried a 65% win probability into the game.

The actual result—a 3-point Buffalo win with both teams scoring significantly higher than expected—fell within the win-probability call but missed the margin. Both offenses outperformed the model's scoring projections: Buffalo reached 33 (3.8 points above the expected 29.2) while Las Vegas posted 30 (5.8 above the expected 24.2). The combined 63 points exceeded the model's combined projection of 53.4.

The 2-point gap between the expected margin (5) and the actual margin (3) represents a minor miss. The model correctly predicted the winner and got within a field goal of the final margin—the kind of variance that occurs in football simulation, where variance is inherent. Buffalo's higher-than-expected scoring output didn't translate to the full 5-point victory the model had positioned, but the Bills still delivered the projected result: a win.

This outcome aligns with what projections should do: identify the likely winner at the correct probability level. The tighter-than-expected final score and the elevated total points suggest both teams' offenses performed above model baseline, but not enough to flip the outcome. Buffalo improved to 5-1, Las Vegas to 3-3.
