The Seattle Seahawks started as an expansion team in 1976 and since the beginning, they have done a good job of bringing in talent through free agency. Let's take a look at the five best free-agent signings in Seahawks history.

Warren Moon

Warren Moon is one of the biggest free-agent signings in history, not just because of what he has done on the field, but also how much he means to the organization. Moon played for the University of Washington and before the 1997 season, he signed with the Seahawks. During the 97 season, Moon threw 25 touchdowns and 3,678 yards.

Moon also played the 1998 season with the Seahawks starting ten games. Moon left the team after the season and played his last two seasons with the Kansas City Chiefs. Moon is still involved with the team, and he was later inducted into the Pro Football Hall of Fame.

Bobby Engram

After spending the first five seasons with the Chicago Bears, Bobby Engram signed with the Seahawks before the 2001 season and he was Mr. consistent. In 2007, Engram caught 94 passes for 1,147 yards and six touchdowns. The 94 receptions broke the team record for catches in a season.

After the 2008 season, Engram left to play for one season with the Kansas City Chiefs where he played in only five games starting zero of them. After the season Engram hung up the cleats and retired from the NFL but he s still considered one of the best wideouts in franchise history.

Michael Bennett

In terms of first contract signed, Michael Bennett is one of the biggest steals of any team. The Seahawks signed Bennett to one year, $5 million deal in 2013 and he was a big reason they were able to win the Super Bowl later that year. Bennett ended up signing a four-year deal during after the 2013 season and he played with the team through the 2017 season.

Once his playing career is over, there is no reason Bennett shouldn't be honored by the team in a big way.

Chris Gray

The Seahawks offensive line was strong in the 2000s and one of the biggest reasons for the success was the play of the offensive line. Gray signed with the Seahawks prior to the 1998 season, and by 2000 he was a full-time starter at right guard.

The rest of the Seahawks offensive line was strong, which made many overlook the play of Gray, but there is no doubt he was part of the glue that held the entire offense together.

Gray made 121 consecutive starts for the Seahawks before hanging up the cleats before the 2008 season.

 Cliff Avril

Cliff Avril was signed one day before Bennett, and he was also a key part of the defense that helped them win a  Super Bowl. Between 2003 and 2006, Avril had 33.5 sacks and helped the team have one of the best defenses in football.

In May of 2018, Avril was released by the Seahawks, but in the short time he spent with the team, he proved why he was one of the best signings by the team in free agency.
