The Seahawks have signed 26-year old DT Quinn Pitcock.  He last played in the NFL in 2007 with the Colts which was his rookie year.  Pitcock has played in 9 games (1 start) in his NFL career and he has 18 tackles, 1.5 sacks and 1 tackle for a loss.  Pitcock actually is coming out of retirement so the Seahawks will need to make sure that he stays motivated and focused.
