There isn't much the Dolphins really need to do on the defensive line, even if they do lose both Paul Soliai and Tony McDaniel to free agency.
The Dolphins have a full starting corps of talent with Kendall Langford, Randy Starks, and Jared Odrick, as well as Phillip Merling returning to a backup role.
Of course, Merling and Odrick have durability concerns in addition to not really being starting-caliber (Merling) or proven (Odrick), and there is some debate as to whether Starks should return to nose tackle if Soliai leaves via free agency.
If Starks remains the nose tackle, then the Dolphins will be pretty much set and will need to add nothing but depth.
If, however, Starks moves back to right end where he was so dominant in 2009 and Soliai is not retained, the Dolphins will have a huge need for a starting-caliber nose tackle.
In free agency, the top nose tackle (though he plays end in Baltimore) is Haloti Ngata, although he is almost sure to be franchised. The next best option could be Aubrayo Franklin (49ers), who worked with Mike Nolan in Baltimore and was brought by Nolan to San Francisco.
Other options include Shaun Rogers, who is available now after being released by the Browns, and Ronald Fields, who worked with Nolan in San Francisco and Denver. Even more names of guys with starting experience or potential include Ma'ake Kemoeatu (Redskins), Gabe Watson (Cardinals) and Alan Branch (Cardinals).
Backup options in free agency include Chris Hoke (Steelers), Ron Edwards (Chiefs), Junior Siavii (Seahawks), and Remi Ayodele (Saints). Ayodele spent time with the Dolphins' coaching staff in Dallas and is the younger brother of former Dolphins linebacker Akin Ayodele.
In the draft, the top nose tackle prospect is Baylor's Phil Taylor, who is someone the Dolphins could seriously consider if they can get back into the second round via trade. Kenrick Ellis (Hampton), Jerell Powe (Ole Miss), Siona Fua (Stanford), Anthony Gray (Southern Miss), and Ian Williams (Notre Dame) are also good nose tackle prospects.
