The Dolphins have only one above average defensive lineman under contract, in Zach Sieler. They have a nose tackle, Benito Jones, who has consistently graded out among the worst in the league. Their only two other defensive linemen under contract are journeymen Matt Dickerson and Neil Farrell.

The Miami Dolphins are losing Calais Campbell to the Arizona Cardinals. This creates a major void both on the field and in the area of team leadership.

Calais Campbell was one of the Dolphins’ best and most inspirational players last season. Campbell, who is entering his 18th season, finished with 52 tackles last season, and 5.0 sacks.
