The decision to replace Kris Richard with Ken Norton Jr., which became official Tuesday, is the most surprising of all the moves Pete Carroll has made over the past week in overhauling his Seattle Seahawks coaching staff.
The question isn't just why he'd fire Richard as defensive coordinator after a trying season in which Seattle lost three Pro Bowlers on that side of the ball. It's also a question of why he'd bring back Norton after passing him over three times for that position dating to 2010, Carroll's first season in Seattle.
Carroll could have made Norton his defensive coordinator that year but instead retained Gus Bradley, a holdover from Jim Mora's only season as Seattle's coach.
