The 1984 Seattle Seahawks season was the team's ninth season with the National Football League. The season opener was moved from Sunday to Monday afternoon on Labor Day to avoid a conflict with the Seattle Mariners baseball game.
The 1984 Seahawks were a well-balanced team on offense and defense. They scored 418 points (26.1 per game), and gave up only 282 points (17.6 per game), both ranked 5th in the NFL. Their point differential of +136 points was third in the NFL; the Seahawks' giveaway/takeway ratio was +24, best in the league. The team's 63 defensive takeaways is the most in NFL history for a 16-game schedule, and the most since the merger.
The team's offense boasted a 3,000-yard passer in quarterback Dave Krieg (3,671 yards), and a 1,000-yard wide receiver in Steve Largent (74 receptions for 1,164 yards). The passing attack more than made up for the loss of star running back Curt Warner, who suffered a season-ending knee injury in the opener.
The Seahawks's defensive line generated an outstanding pass rush, with defensive ends Jeff Bryant and Jacob Green registering 14.5 and 13 sacks, respectively. Safety Kenny Easley led the team and league with 10 interceptions. Easley, Green, and NT Joe Nash made the All-Pro team.
In a wild Week Ten game against Kansas City, the Seahawks intercepted Kansas City's quarterbacks six times, and returned four of them for touchdowns. All the touchdown returns were for over 50 yards. In the game, the Seahawks set NFL records for most yards returning interceptions (325), and most interceptions-for-touchdowns in a game (four).
Seattle would make the playoffs for the second straight season. They defeated the defending Super Bowl champion Los Angeles Raiders 13-7 in the wild card round avenging their 1983 loss. However, they were not able to advance past the Miami Dolphins, as they lost in Miami 31-10 to a powerful Dolphins squad led by record setting second year quarterback Dan Marino, who they had defeated in the playoffs the previous season.
