Lutui: The Seahawks wanted a veteran guard at an affordable price after releasing Robert Gallery. They considered Steve Hutchinson, but he signed with Tennessee. Lutui has considerable starting experience with the Arizona Cardinals, but weight issues contributed to his decline into a backup role. Lutui and Seahawks coach Pete Carroll were together at USC. Can the Seahawks get more from Lutui than the Cardinals were getting from him recently?
Ruud: Ruud, 28, was a longtime starter in Tampa Bay before signing with Tennessee last season. He played nine games for the Titans, starting all of them. But a groin injury forced him onto injured reserve. Seahawks defensive coordinator Gus Bradley was with Tampa Bay when Ruud played for the Buccaneers. Bradley coached linebackers for part of Ruud's tenure there. That connection means the Seahawks should have a good idea what they're getting. Ruud's arrival comes after the Seahawks watched starting middle linebacker David Hawthorne sign with New Orleans. I would expect Seattle to address linebacker in the draft as well.
Lewis: Lewis returns for what will be his fourth season with the Seahawks. He played in 10 games last season, starting one, and participated in about 40 percent of the defensive snaps overall. Lewis adds depth and familiarity to the secondary.
On a side note, Lutui had worked out for the San Francisco 49ers earlier in free agency. San Francisco continues to look for veteran depth at guard.
