Russell Okung came from Oklahoma State as a First Round Pick (Sixth Overall) in 2010, and he was immediately slotted in as the Seattle Seahawks’ starting Left Tackle. Okung played for Seattle for five years, and as long as he was wearing a helmet, he was starting. He provided stability to Russell Wilson's left side, and he was a significant factor in the Seahawks back-to-back AFC Championships, and their Super Bowl XLVIII win.
Brandon Mebane did not have a career that stood out, but not every football player needs to be a superstar. He was solid and dependable, and every football player needs glue guys like Mebane.
Julian Peterson was with the San Francisco 49ers for five years, going to two Pro Bowls (2002 & 2003) before he signed with the Seattle Seahawks in 2006.

Coming out of Arizona State as a Seventh Round Pick, John Harris made the Seattle Seahawks roster as a rookie.
Jim Zorn went undrafted in 1975 out of Cerritos College, but the Dallas Cowboys gave him a shot but cut him before the season started. The Los Angeles Rams tried him out, but that did not work out either. 1976 would be a different story, as he was signed by the Seattle Seahawks, who were an expansion team, and not only would he make the roster, he became their starting Quarterback.
Mack Strong played 201 Games (his entire NFL career) with the Seattle Seahawks, which was an impressive feat for anyone, especially a player who was an Undrafted Free Agent.

The son of former NFL Fullback, Mosi Tatupu, Lofa Tatupu would exceed his father’s career, first by being an All-American Linebacker and two-time National Champion at USC, and then for his work on the professional ranks with the Seattle Seahawks.
At the University of Michigan, Steve Hutchinson helped the Wolverines win a title in 1997 and was an All-American in 2000. The Seattle Seahawks were fortunate that the Offensive Lineman fell to them with the 17th overall pick of the 2001 Draft.
Helping the Virginia Tech Hokies win two ACC Titles, Kam Chancellor’s next stop was Seattle, where he arrived as a 2010 fifth round pick.
Before there was Marshawn Lynch, and before there was Kurt Warner, there was Curt Warner, who was arguably the Seattle Seahawks’ first star Running Back.
When Mike Holmgren left the Green Bay Packers to coach Seattle, he knew that Matt Hasselbeck, the backup to Brett Favre, was NFL ready. He was right and engineered a trade for the pivot, who took over as the starting QB in 2001.
Many in the city of Buffalo are still upset that they traded Marshawn Lynch for a pair of draft picks in 2010, and in that year’s playoff, “Beast Mode” became a nationally known figure.

Rufus Porter went undrafted in 1988, but the Linebacker from Southern landed a job with the Seattle Seahawks, where he was a Pro Bowl Selection as a Special Teams player as a rookie. This was a good start, but Porter found a more significant role with the team in later years.
In terms of longevity, Chris Gray is one of the most tenured members in the history of the Seattle Seahawks.
Max Unger arrived in Seattle, coming north as Second Round Pick from Oregon in 2009.
Michael Bennett was not drafted after he left Texas A&M in 2009, but he signed with the Seattle Seahawks. He was released before he could play a down.
