The Seahawks were the big winners of Sunday’s early lineup, as their 26-21 comeback victory over the Jets secured them sole possession of first place in the NFC West at 7-5.

Seattle will lead the division entering Week 14 regardless of what other teams do, but the Cardinals’ loss to the Vikings ensured that Mike Macdonald’s team will experience some separation.

The 49ers and Rams, meanwhile, are in danger of falling two games out of the division lead with losses on Sunday. San Francisco is hoping to get back on track with Brock Purdy, but a tough matchup in Buffalo could put the team in a difficult situation to recover from with no games remaining against the Seahawks.

The Seahawks and 49ers split their season series so the head-to-head tiebreaker would tie the division record. Meanwhile, Seattle can secure the tiebreaker over the Cardinals with a win against Arizona in Week 14. With five games left, Geno Smith and Co. are in a better position than anyone to win a crowded NFC West.
