The only team to beat the Seahawks at home in the last two seasons? That would be the Arizona Cardinals, who won, 17-10, at CenturyLink Field in Week 16. The 49ers played the Cardinals the following week, and we asked coach Bruce Arians and cornerback Patrick Peterson how they pulled off the upset.
* Arians: "I thought stopping the run was huge in that game. We wanted to win both lines of scrimmage, and I felt like our defensive line stopped them pretty good. And our third-down conversion rate was outstanding on defense, getting off the field."
* Peterson: "Honestly, just jump on 'em early. Seattle is a pretty good team and the things they like to do, they do it well. I believe if you shut down those things early, get 'em into a one-dimensional team, which is throwing the football, I think you have a pretty good opportunity to win it."
Indeed, Seahawks running back Marshawn Lynch had a decent game in carrying the ball 18 times for 71 yards. But he didn't get into the end zone and he had 10 carries of 2 yards or fewer. Furthermore, quarterback Russell Wilson had a bad day (108 passing yards; 49.6 passer rating), and the Seahawks had seven three-and-out series. They were 2-13 (15 percent) on third downs. As Peterson said, the Cardinals got out to an early lead. But they certainly never had a big lead; their widest margin was seven points, which occurred when they scored a touchdown with 2:13 left.
