Seahawks -2.5 (-105) ⭐⭐⭐⭐
With the 49ers winning six straight entering Saturday, some people might believe the wrong team is favored in this clash for the NFC’s top seed, but I’m siding with Seattle’s sturdier defense over San Francisco’s unit that has allowed 338.9 yards per game on the year (19th in NFL).
The Seahawks are 7-1 against the spread in road games while the 49ers are just 3-3-1 ATS at home.
Jaxon Smith-Njigba Over 94.5 receiving yards (-114) ⭐⭐⭐⭐
Fresh off allowing a 138-yard outburst to Bears rookie WR Luther Burden III, the 49ers feel particularly susceptible right now to what Jaxon Smith-Njigba can do to their secondary.
JSN has cleared this receiving line in 11 out of 16 games this season (68.7%), while the San Francisco secondary has allowed 2,419 receiving yards to opposing wideouts (11th-most in NFL). DraftKings lists this line at 98.5 yards, so we’re playing the parlay at FanDuel to attack the prop at Over 94.5 yards.
Christian McCaffrey Over 46.5 receiving yards (-114) ⭐⭐⭐⭐
Seattle has allowed 601 receiving yards to opposing running backs this season, sixth-most in the NFL, making the Seahawks a prime target for Christian McCaffrey’s skill set.
CMC has recorded more than 46.5 receiving yards in 10 out of 16 games this season (62.5%) and a projected negative game script would correlate to more passing involvement for San Francisco skill players.
