The Seahawks have won four in a row on the road to start the 2019 season, and have won eight of their last nine against the 49ers.
But it was the last game in San Francisco that was the beginning or end of streaks — the 49ers’ 26-23 overtime win last Dec. 16 marked the last time the Seahawks have lost on the road in the regular season, and snapped a string of eight straight wins for Seattle over the 49ers dating to late in 2013.
And now here the 49ers are again, at 8-0 the only unbeaten team left in the NFL with a point differential of plus-133 that is the second-best (behind only the 172 of New England) and favored by six against the 7-2 Seahawks in a game that will go a long way toward determining the winner of the NFC West.
