It's fair to say that Cullen Jenkins is one of the best, if not the best, 3-4 pass rushing defensive linemen in the league. The only better one who comes to mind is Haloti Ngata, who is simply the best 3-4 (and maybe regardless of scheme) defensive lineman in the NFL.
Jenkins, however, comes with some red flags. The first is that he has only played one full regular season as a starter since coming into the league seven years ago. Secondly, he is 30 years of age, so doesn't have that much time left playing what is a physically taxing position.
For a team to invest in Jenkins they would need to be confident that he could stay healthy enough to contribute on a regular basis. He is not going to come cheaply because he will be highly coveted. Jenkins is the biggest risk on the free agent market but definitely has the biggest reward.
He has the ability to take over a football game up front, using that ability to notch himself 29 career sacks. Even after starting only eight games last season he still managed seven sacks. That was somewhat an anomaly as he benefited from the influence of Dom Capers on the sidelines and a beast such as BJ Raji alongside him.
Even so, Jenkins has had three or more sacks in five of his seven NFL seasons. During one of the seasons that he didn't, he had 2.5 sacks in only four games.
Cullen Jenkins brings a lot of intensity, experience and size (6'2" 305 pounds) to the defensive side of the ball. More importantly, however, he brings sacks, disruption and a unique set of skills.
Jenkins will be the most coveted player in free agency, irregardless of the risks that accompany him.
