The Seahawks were once known for their dominant defense with a secondary dubbed the Legion of Boom, and featured some of the best at each position, including Cliff Avril, Michael Bennett, Bobby Wagner, Richard Sherman, Earl Thomas, and Kam Chancellor. Only Wagner will still be on the field Saturday night.
Furthermore, several of the architects of that defense are no longer there, as guys like Gus Bradley and Dan Quinn have taken jobs elsewhere. And of course there’s Kris Richard, who was the Seahawks defensive coordinator last year and was fired before taking a similar role in Dallas.
