The Seahawks own one of the biggest home-field advantages in the league. They used it to paste the 49ers, 42-13, in the NFC West rivals last meeting in December.
Yet, Seattle is only a 3-point favorite over the visiting 49ers on Sunday. The Seahawks have covered the spread in 10 of their last 11 home games and are 16-4 ATS in their last 20 home games.
San Francisco went 6-3 against the spread on the road last season and has won three of four against the Seahawks under coach Jim Harbaugh.
The 49ers were impressive, especially offensively, in an opening win over the Green Bay Packers. Quarterback Colin Kaepernick threw for more than 400 yards in the win.
The Seahawks’ offense got off to a slow start in their opening win at Carolina, but the defense picked up right where left off last season.
Seattle is 10-1 ATS in its last 11 games at home, while San Francisco has struggled to a 1-5 ATS mark in 6 games at Seattle.
