The 2017 season was a disappointment for the Seahawks. A five-year playoff streak was snapped when Seattle finished the season with a 9-7 record. It was the first time Seattle didn't win 10 games since 2011. More of a "win now" approach was taken where short-term interests took a higher priority in an effort to get to the Super Bowl for the third time in five years. A 2018 second round pick and wide receiver Jermaine Kearse were traded to the Jets for defensive lineman Sheldon Richardson at the preseason roster cutdown. Some of the deficiencies in the offensive line were addressed by acquiring disgruntled left tackle Duane Brown, whose lengthy holdout lasted until the seventh week of the regular season, from the Texans for 2018 third round and 2019 second round picks. Seattle also received a 2018 fifth round pick in this transaction. A roster containing several high-priced contracts finally caught up with the Seahawks. Uncharacteristically, contracts were restructured to help accommodate these moves. Unlike many teams, the Seahawks had avoided pushing current cap obligations into the future until wide receiver Doug Baldwin and quarterback Russell Wilson reworked their contracts. A defense that has been consistently among the league's best became vulnerable. The Seahawks went 3-4 in the final seven games after strong safety Kam Chancellor and cornerback Richard Sherman were sidelined respectively with neck and Achilles injuries. A consequence of falling well below expectations had head coach Pete Carroll shaking up his coaching staff. Eight coaches, including offensive coordinator Darrell Bevell, defensive coordinator Kris Richard and offensive line coach Tom Cable were let go. Brian Schottenheimer takes Bevell's place. Ken Norton, Jr., who was Seattle's linebackers coach from 2010 to 2014, returns as defensive coordinator after an unsuccessful stint running the Raiders defense for the better part of the last three seasons. The Seahawks are facing challenges on multiple fronts in their quest to keep their championship window open. A suddenly more competitive NFC West gives the Seahawks less margin for error. The Rams, the reigning NFC West champions, earned their first playoff berth since 2004. The 49ers appear to be a team on the rise. Quarterback Jimmy Garoppolo, who was acquired from the Patriots at the trading deadline, led the 49ers five straight victories to close the season once he was inserted into the starting lineup. The Legion Of Boom's Doom Seattle's vaunted secondary, the Legion of Boom, was the cornerstone of a dominant defense during consecutive Super Bowl appearances in the 2013 and 2014 seasons. The franchise's only league championship came during the 2013 season. Keeping the mainstays of the group together for an extended period of time after lucrative second contracts were set to expire was always going to be a difficult, if not an almost impossible task.
