Cullen Jenkins, 32, is 6'2, 305, and is a former John Schneider undrafted free agent signing, then with the Packers. He played in Green Bay from 2003 to 2010, so there's a familiarity there that possibly gives Schneider the inside track. Jenkins is getting up there in age, but still had a pretty strong year with the Eagles in 2012 - he had 4 sacks and 26 tackles in 16 starts in 2012 and 5.5 sacks, 32 tackles in 16 starts in 2011 - he is ranked 7th among defensive tackles on NFL.com's free agent list, right in the same grouping as Sedrick Ellis, Glen Dorsey, Alan Branch, Chris Canty and Terrance Knighton.
I originally thought that Jenkins would stay out east - he had met with the Giants and many speculated that he'd meet with the Packers, but he's making a west coast swing to see if anything fits. He offers positional versatility as an end or tackle, after playing in a 3-4 for the past couple of seasons. More important, his specialty is rushing the passer, a skill the Seahawks are looking to add.
