With the defensive players at the Combine about to take the stage and FA 2 weeks away, this are the key areas that I see potentially being addressed on defense:
1. NT. I don't see Wilfork coming back at reasonable strength in 2014. He could be restructured moving some of his base contract to NTLBE (freeing up around $4M in cap space), which would buy some time to assess his status, or he could be cut, freeing up $7.5-8M in cap space. In the latter case, a veteran FA such as Linval Joseph or Red Bryant could be added for considerably less money. Sealver Siliga looks like a keeper as a rotational player. Isaac Sapoaga will undoubtedly be an early cap casualty. I don't personally like the idea of going after a guy like Louis Nix in the draft, but if Justin Ellis was available in the right range he could be an option.
2. 3-Tech DT. Tommy Kelly will hopefully be recovered from his ACL injury, Chris Jones showed nice potential as a rookie, and Armond Armstead is a dark horse. This isn't necessarily an acute need, but I would personally prioritizing adding a disruptive 3-tech like Aaron Donald or Dominique Easley. I think that either could add an critical element of disruption that has been missing from our interior defense.
3. Rotational DE. I think this is a priority, and the draft is very shallow at this position. Free agency is very deep at this position. One of Carlos Dunlap / Michael Johnson should be available, and the Pats might be able to afford them. Corey Wootton is a good lower-cost alternative if he hits FA. Everson Griffin is a dark horse candidate.
4. DE/OLB / Sub Rusher. Not a major priority, but if a prospect like Marcus Smith was available in the right range, he could add considerable value. Tyler Starr is a day 3 option.
5. LB. I think Brandon Spikes is gone and Dane Fletcher will be re-signed. There's room for another LB, preferably one who can play in space and be moved around to create mismatches. Christian Jones is my top candidate for this role. This role could also overlap with #4 above.
6. Strong Safety. Steve Gregory was ok in 2013 but leaves room for an upgrade, and has a fairly hefty cap hit. Duron Harmon will hopefully develop, but is more of a backup FS behind Devin McCourty. Tavon Wilson is a dark horse. I think the FA options will be too expensive to warrant the investment, but I think there is room to upgrade at this position in the draft. Kyle Fuller, Deone Bucannon and Antone Exum are all intriguing options. Jonathan Dowling is a dark horse prospect.
7. Big DB. I assume Aqib Talib will be re-signed, but I want some depth behind him. Kyle Fuller, Bashaud Breeland, Stanley Jean-Baptiste, Antone Exum, Aaron Colvin, Jonathan Dowling and Dontae Johnson are all options.
I don't necessarily expect all of these to be addressed, but I think there will be decisions to be made about all of these areas and how to prioritize them.
