Pittsburgh Steelers vs Tampa Bay Buccaneers — Win Probability

Model's Tight Call on Steelers-Buccaneers Held Up; Pittsburgh Won as Projected Favorite

The model's pregame projection proved directionally sound in Pittsburgh's 26-19 victory over Tampa Bay, though the Steelers' actual margin of victory was notably wider than expected.

Before kickoff, the model favored Pittsburgh with a 55% win probability and projected a 1.5-point margin—expecting a final score of 20-18.5 in the Steelers' favor. That projection aligned exactly with the market's published spread, positioning both the model and sportsbooks in agreement on a closely matched contest.

The game did not develop as a nail-biter. Pittsburgh won 26-19, a 7-point margin that exceeded the model's expected spread by 5.5 points. The Steelers' actual 26 points came in 6 above their projected 20, while Tampa Bay's 19 matched their expected total almost precisely at 18.5.

This was not an upset—the model correctly identified Pittsburgh as the favorite and the winner. But the gap between expected margin and actual result reveals something specific: the model underestimated the distance between these teams. A projection of a one-score game that resolves as a clear 7-point victory suggests the Steelers' performance edge was greater than the pregame inputs captured. Pittsburgh's superior execution or Tampa Bay's underperformance relative to expectation created a 5.5-point miss on the margin.

The model's call that Pittsburgh would win proved right. The confidence level—a 55-45 split—was appropriate for a closely matched pair, and the result stayed within the realm of what a small-edge favorite typically produces. But the Steelers separated themselves more decisively than the numbers anticipated, turning a toss-up-plus into a comfortable road victory. Correct direction; wider outcome than projected.
