49ers 32, Seahawks 29: Four Takeaways Sink Seattle in Thriller

The San Francisco 49ers walked into Lumen Field and left undefeated, beating the Seattle Seahawks 32-29 in a game that flipped on turnovers. Four Seattle giveaways proved decisive, with the 49ers converting takeaways into points and surviving a late push from the defending champs.

Seattle had chances. The Seahawks turned a 49ers turnover into a game-tying touchdown, and the back-and-forth nature of the afternoon kept the outcome in doubt until the final possession. But sloppiness cost the home side in a game that was there for the taking.

How our picks graded

Spread — Seahawks -3.0: LOSS. Seattle not only failed to cover, it lost outright by three. Our number had Seattle winning by a touchdown; the market was closer to the truth than we were.

Moneyline — Seahawks -174: LOSS. The model's 66.15% confidence in a Seattle win did not hold. The 49ers, at +146, were the better side on the day.

Total — Under 46.5: LOSS. With 61 combined points, the under was never really in play. We projected a 23-16 Seahawks win — a 39-point game — and the actual result blew past that by 22 points.

Projected scoreline — Seattle 23, San Francisco 16: MISS. The final was 32-29 the other way, a 14-point swing from our exact-score expectation.

What it means going forward

This was a clean sweep of misses, and the lesson is straightforward: we leaned too hard on Seattle's slow tempo and stingy defense while underestimating how much San Francisco's takeaway-driven offense could dictate pace. When a defense-first home team is priced at -3.0 against an undefeated opponent, the margin for error is razor-thin. Expect us to weight turnover differential and opposing defensive playmaking more heavily in NFC West spots going forward — and to be more cautious laying short numbers with low-tempo favorites.
