The Seahawks were supposed to be a dominant defensive team under former head coach Pete Carroll. For a while, they were definitely that, fielding the best unit in the league for four straight seasons when they were at their very best (2012-2015). However, after that fateful 2015 season this group started to fall off and they were never able to regain their footing or even come close to being an elite defense again in the Carroll era. In fact, the last few years they had become one of the worst defenses in the NFL.
