Seattle had 28 interceptions and an opponent passer rating of 63.4, one of just 15 teams since 2000 to hold opposing passers to 65.0 or less.
Cornerback Richard Sherman led the NFL with eight interceptions, including four over the final three games. Earl Thomas also was a first-team All-Pro pick, while fellow safety Kam Chancellor was a second-team choice.
The Seahawks are tied for seventh with 101.6 rushing yards allowed per game, giving up 25 or less in two of their last three.
Seattle has won four of five home meetings, including the postseason victory three years ago. If they want to beat the Saints this week they will need to slow down Drew Brees.
