SEATTLE -- With a couple of exceptions, nobody on the San Francisco 49ers knows better than defensive lineman Arik Armstead just how hard it is to beat the Seattle Seahawks at Lumen Field.
For all of Armstead's eight years in the NFL, he has been part of teams that have come to Seattle and left with disappointing losses. There was only one notable exception, in 2019, when the Niners beat the Seahawks in a thriller to clinch the NFC West division and the NFC's No. 1 seed.
After Thursday night, there are now two notable exceptions, as the Niners jumped on the Seahawks early and held on for a 21-13 win.
