The Seahawks defense hasn’t been up to the standards they set a few years ago. There’s no getting around that. When you compare last year’s secondary to the Legion of Boom, well, it just doesn’t measure up. As Lee Vowell wrote, the defensive backs are far from the worst in the league, though. Seattle has a bigger problem than their pass defense, though
Let’s look a the numbers, shall we? Last year Seattle ranked 19th in passer rating allowed (94.3), tied for 14th in touchdown passes allowed (26), and had just 12 picks. That isn’t LOB quality, but it isn’t the 49ers, either.
