After nearly a decade of trash seasons, they reached the mountain top, capped by a dominating Super Bowl win. The saying goes, defense wins championships, and Seattle proved that with a unique unit that rivaled the greats. While commanding defenses of the past typically revolved around a strong front seven, the Seahawks destroyed teams with a hard-hitting secondary ready to knock heads, gaining the nickname the Legion of Boom. It’s a plan Seattle put in motion years earlier.
