Tampa Bay Buccaneers vs Cincinnati Bengals — Win Probability

Bengals edge Buccaneers as model nails spread, underestimates scoring

Cincinnati's 33-27 win over Tampa Bay played out almost exactly as the pregame model predicted in terms of margin, though both teams scored more than expected.

The model projected Cincinnati to win by 3.5 points with a 60% win probability, matching the market's published spread of 3.5 points. The Bengals won by 6, meaning the model's directional read was sound—it correctly identified Cincinnati as the favored team and got within 2.5 points of the actual margin.

Where the model underestimated was total scoring. It projected Cincinnati at 27 points and Tampa Bay at 23.5, for a combined 50.5. The actual total was 60 points—nearly a full touchdown higher than expected. Cincinnati scored 6 more than projected (33 vs. 27), while Tampa Bay exceeded its forecast by 3.5 (27 vs. 23.5).

This gap between expected and actual scoring tells two stories. First, the model's margin prediction held up well despite the scoring miss—a result that can happen when both teams exceed projections roughly proportionally. Second, the model and market aligned perfectly on the spread itself, suggesting the pregame consensus got Cincinnati's edge right even if the total offensive output was harder to pin down.

For a Week 1 matchup with significant uncertainty around team composition and readiness, the 3.5-point miss on margin is negligible. The model called Cincinnati to win by more than Tampa Bay, and that's what happened. The higher-than-expected scoring could reflect early-season offensive tempo, reduced defensive cohesion, or simply variance in a small sample. The projection held where it mattered most: the winner and the spread.
