Walter Football has ranked the Free Agents, a few I'm interested in are - in no particular order:

Note the Panthers have a swag of LBs and a DE we could be interested in. They are also notoriously cheap. San Diego has more talent than they can franchise too.

1. Manny Lawson, OLB, 49ers. Age: 27.
   Manny Lawson isn't the greatest pass-rusher in the world, but he does so many other things very well. Moving on to a team with a 4-3 defense might be ideal for the former first-rounder.
   
   
2. Rocky McIntosh, OLB, Redskins. Age: 28.
   A decent weakside linebacker in the 4-3, Rocky McIntosh was one of many Redskins who were lost in the new 3-4 look. McIntosh will have more success next year as long as he stays away from teams running the 3-4.
   
   
3. James Anderson, OLB, Panthers. Age: 27.
   James Anderson had a very good year at strongside linebacker, recording 130 tackles and 3.5 sacks.
4. Charles Johnson, DE, Panthers. Age: 25.
   One of the top young defensive free agents on the market, Charles Johnson became the fifth Panther ever to record double-digit sacks (12) in 2010. He was dominant from the left end position all year. Carolina cannot afford to let him go.
5. Eric Weddle, S, Chargers. Age: 26.
   Eric Weddle is due for a massive contract. Excluding Ed Reed and Troy Polamalu, Weddle might be the best safety in the NFL (though Nick Collins may have something to say about that).
   
   
   
   
6. Dawan Landry, SS, Ravens. Age: 28.
   Already a terrific run-support safety, Dawan Landry improved his coverage skills this past season.
   
   
7. Quintin Mikell, SS, Eagles. Age: 30.
   A Pro Bowler who excels both in both run support and pass coverage, Quintin Mikell will be offered a big contract this offseason.
   
   
8. Danieal Manning, SS, Bears. Age: 29.
   In addition to being a solid strong safety, Danieal Manning averaged 24.7 yards on his kickoff returns this year.
   
9. Vernon Gholston, DE, Jets. Age: 25.
   Vernon Gholston was a huge bust for the Jets as the No. 6 overall pick in the 2008 NFL Draft. I'm listing him at 2.5 stars, however, for three reasons. First, Gholston is only 25, and has a ton of upside and athleticism. Second, I'd like to see what Gholston can do in a traditional 4-3. And third, defensive ends usually take a while to transition to the NFL. Granted, Gholston has shown nothing, but there's a slim chance he could be a very late bloomer. He's worth the risk.
   
10. Antonio Cromartie, CB, Jets. Age: 27.
    Antonio Cromartie has his ups and downs, but overall is a decent, play-making No. 2 cornerback.
    
    
11. Josh Wilson, CB, Ravens. Age: 26.
    Josh Wilson was a pleasant surprise for the Ravens this season, as he came out of nowhere to become a reliable starter for them.
    
    
12. Carlos Rogers, CB, Redskins. Age: 30.
    Carlos Rogers didn't play well this season because of a myriad of injuries. If healthy, he's still a solid starting cornerback.
    
    
13. Richard Marshall, CB, Panthers. Age: 26.
    Richard Marshall whined about not receiving a long-term extension this past offseason. He subsequently struggled throughout the 2010 season, though some of that blame falls on Carolina's lacking pass rush.
