Seattle offense looked terrible last week but defense bailed Seahawks out. That defense always shows up at home but the offense is also infinitely better, averaging over 30 points while going a perfect 8-0 last year. This is the loudest stadium in the NFL and a nightmare for visiting teams, as the 49ers discovered in a 42-13 beatdown last year. And yes, that was after Kaepernick took over at QB for Niners.
