Welcome back, Chris.
The Seahawks have re-signed defensive end Chris Clemons. Clemons was a part of the Super Bowl 48 Championship team and put up 38.0 sacks in four seasons from 2010-2013. He had three-straight 11 sack seasons from 2010-2012 (11.5 in 2012) then 4.5 in 2013. He has 11 sacks in the last two years in Jacksonville (8.0 in 2014, 3.0 in 2015). He's 34 years old.
It will be interesting to see how much money is guaranteed, and if Clemons will have to compete for a roster spot (seems likely). If he makes the team, he figures in to the Seahawks defensive line rotation and adds some depth to the pass rush unit. His production took a huge dip in 2015 but Seattle obviously liked what they saw enough to bring him back, and Clemons evidently didn't hold too hard of feelings for the Seahawks releasing him after the 2013 season.
With Michael Bennett, Cliff Avril, and Frank Clark, Clemons adds to the group that also includes Cassius Marsh, Jordan Hill, Ryan Robinson, and Josh Shirley.
Because Clemons was waived by the Jaguars, he will not factor in to the compensatory pick formula.
