The Seahawks are bringing back a player who was a key part of their secondary in 2017 and 2018, having signed cornerback Justin Coleman on Thursday. 

"I'm very familiar with the people around here, the organization, the culture," Coleman said after signing on Thursday. "I've been here, so I know what this organization expects and what they ask out of me. Pete Carroll, I feel like is one of the greatest coaches. And I just missed this place. I missed the energy that this place brings, I missed the fans, missed the players, missed the coaches, everybody. I'm just ready to get going."

Coleman, who came into the league as an undrafted free agent in 2015, spent his first two seasons in New England before the Seahawks acquired him in a 2017 trade. In two seasons with the Seahawks, Coleman thrived in the nickel cornerback role, appearing in all 32 games while recording 19 passes defensed, three interceptions, a forced fumble, 98 tackles and two defensive touchdowns, once of which ended with him in an oversized Salvation Army kettle during a Christmas Eve victory in Dallas. 

Coleman's success in Seattle led to a big payday in free agency in 2019, with Coleman signing with the Detroit Lions, where he spent two seasons before joining the Dolphins last season. 

Coleman said his two years in Seattle "gave me confidence just to go out there and play against anybody. It propelled my career forward."

If Coleman is indeed returning to Seattle to play the nickel spot, he'll likely compete with Marquise Blair and Ugo Amadi, who have competed at that spot over the past two seasons when Blair was healthy. Coleman does also have experience playing as an outside cornerback, having started at right cornerback for the Lions in 2019.

Coleman was also a top special teams contributor during his two seasons in Seattle, recording 20 special teams tackles, including a team-high 12 in 2018.
