Seattle allows 450 total yards defensively
While Boye Mafe will have a great game, the rest of the defense is still a bit of a mess. Seattle being Jekyll and Hyde defensively happened in 2022, too. After being terrible through the first five games last year, Seattle then had a stretch of four games where they gave up no more than 329 total yards and had two games of 262 yards or fewer. We thought the Seahawks' defense might have been fixed then, too.
After looking pretty bad through the first three games of 2023, Seattle had a three-game run of being solid and looking fixed. Then the Cleveland Browns came to Seattle in Week 8 and even with a backup quarterback ran for 155 yards and gained 385 total yards. Then the hammer fell in Week 9 and Seattle allowed 515 total yards to the Ravens including 298 rushing yards. Seattle went from being one of the best teams in the NFL in yards allowed per rush to 21st in two weeks.
The Commanders have a good offensive coordinator in Eric Bieniemy and he will know how to exploit any defensive weakness of Seattle. Washington is capable of running fairly effectively and throwing the ball. Plus, if Washington gets some decent blocking when Sam Howell drops back, Washington can score 30 points on the Seahawks which might be enough to win.
Washington is 12th in rushing yards per attempt (4.3) and Howell is completing 66.6 percent of his passes. Seattle has lots of talent on defense, but they haven't played cohesively in the past two weeks. That trend likely continues into Week 10 and the Seahawks surrender a ton of yards.
