49ers Seahawks Odds: Spread, Moneyline, Over/Under

When using the 49ers Seahawks odds table above, click the dropdown menu to switch to moneylines or over/unders. 

Betting on the point spread is when you wager on how many points a team will win or lose by. A “plus” sign in front of the spread is the underdog, and a “minus” sign is the favorite. The 49ers need to win by four points or more if you bet on them against the spread, as they’re priced as a cheap 3.5-point road favorite at most shops. Conversely, a spread bet on the Seahawks would need Seattle to lose by three points or win outright.

The total is the number of combined points that the two teams will score. Bettors can bet “over” or “under” on how many total points will be scored in the game.

49ers Seahawks Odds: Betting Insights

Which Team Will Cover The Spread?

After finishing with the fourth-highest Dropback EPA in Week 14, the betting market has fallen in love with 49ers rookie QB Brock Purdy. As San Francisco aims to clinch the NFC West with a victory, we’ve seen the spread shift above the key number of a field goal.

Nevertheless, Kyle Shanahan’s offense employs the league’s 10th-highest rushing rate, and that will likely remain the case with Purdy dealing with an oblique injury. Shanahan hasn’t declared Purdy as the starter for this week, yet he did note that Purdy wouldn’t worsen his injury by suiting up in Seattle.

Keep in mind, Seattle is allowing the 12th-lowest Rushing Success Rate across the NFL. For context, a play is successful if teams produce:

  • 50 percent of the yards needed to move the chains on first down
  • 70 percent of yards to gain on second down
  • 100 percent of yards to gain on third or fourth down

Hence, the 49ers may not be as efficient on the ground as one would initially expect. But Al Woods’ absence on the Seahawks’ defensive front hurts that notion.

On the flip side, Geno Smith is up against arguably one of the league’s premier defenses, especially against the pass. While he’s exceeded expectations in his ninth season as a pro, he may not be as fortunate this time against DeMeco Ryans’ pressure-heavy unit.

Will The Total Go Over Or Under?

If you couldn’t tell from the context above, expect both offenses to struggle. Couple that with San Francisco’s tempo ranking No. 25 in neutral situations (per Football Outsiders), and I’d anticipate a methodical pace from Shanahan with his rookie in a hostile environment as well.

Final Thoughts

I bet under 43.5, which you’ll find in our aforementioned Discord betting channel. Play it down to 43. Good luck with your own wagers on 49ers Seahawks odds.
