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.
