The 49ers and Seahawks face off in a pivotal NFC West matchup that will determine the playoff picture going forward.

The NFC West wouldn't be in contention at all had San Francisco not sputtered out of the gate — due in large part to injuries and a comparatively feeble defense relative to years past. The heavy preseason favorites to win the NFC West are just +110 to win their division in the marketplace now after a shaky 2-3 start.

Meanwhile, the Seahawks have been solid, winning every game in which they were favorites before losing to the Lions as big underdogs on Monday Night Football. That was before a loss to the Giants on Sunday had prognosticators questioning whether their defense has truly turned the corner. That unit had ranked near the bottom of the league for the last two seasons of Pete Carroll's tenure as coach, with the team riding a postseason appearance in 2023 on the backs of Geno Smith and their offense.

With that loss against the lowly Giants — and the pedigree of the 49ers, despite this season's results — the Seahawks are 3.5-point home underdogs tonight.

And small home underdogs of +4 or less on primetime have returned bettors roughly 6% in ROI since the 2017 season.

If you had wagered $1,000 per game on the moneyline of every home underdog in a primetime game (Thursday Night Football, Sunday Night Football or Monday Night Football) during this timeframe, you'd be up $5,560.

Of course, you lose on the aggregate more than you'd win — that's what happens when you're betting on plus-money. But because of underdog ML payouts, this type of bettor would have returned 5.8% on every dollar wagered since 2017.

An interesting note here as well: Seattle is among 10 teams that are home underdogs this week. If that trend persists, that would be the most in a single week since 2020 and the most before Week 10 since 2004, according to our data guru Evan Abrams.
