Much of what's made Seattle so formidable at home over the years — the "Legion of Boom," the "12th Man" — won't be at the Seahawks' disposal, and the Vikings' offense can make some big plays against a Seattle defense that's struggling. But the biggest reason the Seahawks are undefeated is a quarterback who's having the best season of his career, and Russell Wilson will make the difference in a close game.
THREE BIG STORY LINES
Dalvin Cook vs. 'Let Russ Cook'
The Vikings have run the ball more often than almost any team in the league during neutral game situations (when they're not trying to run out the clock or throw on every down to come back, in other words). They'll face a Seahawks team that's gone from a run-heavy offense to an aggressive downfield passing game. Wilson might be the league MVP through the first quarter of the season and will test the Vikings' young secondary.
No '12s' for this trip to Seattle
For the third straight year, the Vikings will play a prime-time game at CenturyLink Field — but this time, they'll do so without having to navigate the stadium's famously noisy environment. The Seahawks won't have their "12th Man" at their disposal, with no fans being admitted to the stadium, so the Vikings' trip to one of the league's loudest venues will be strangely quiet.
Vikings try to keep offense rolling
After surpassing 30 points against the Titans and Texans, the Vikings could find some success against a young Seattle defense that hasn't been as stout as in past years. The Seahawks are starting a number of young corners and have allowed more yards than any team in the league.
