The Seahawks defense is very different on the road than at home, particularly their run defense which is kind of up and down overall to be honest. They rolled the 49ers last week and a listless Vikings this week but the week before they somehow escaped with a win at Carolina despite getting outplayed pretty solidly, having given up about 450 yards to a pretty mediocre Panthers offense.
I'd rather play the Vikings of course but the Seahawks are very beatable, as long as we (Dak) don't beat ourselves.
