National Football Post published the full list of unrestricted defensive free agents this morning.  It is pretty slim pickings since the CBA is no longer in existence- with most of the players being older because the service time to become an unrestricted free agent being increased, but there are a couple of guys that would help the Titans:

Packers DE Aaron Kampman- The Packers switched to a 3-4 this past season and in doing so moved Kampman from end to linebacker.  He struggled in that role but would obviously be a DE with the Titans.  Kampman averaged 12+ sacks in the three seasons prior to the switch.  He turned 30 in November so he could have a couple of good years left in the tank.

Bears DE Adewale Ogunleye- Ogunleye is a solid pass rusher who has an awesome name.  He turns 33 in August but is still a solid pass rusher.  He is not a guy you would want to give a long term deal, but he could come in and help this team in 2010.

Panthers DE Julius Peppers- Peppers is the youngest of these three and the best.  The reason I haven't listed him until now is that he is going to get silly money, and we all know that isn't coming from the Titans.

Cardinals LB Karlos Dansby- Much like Peppers, Dansby is going to command a boatload of money, but acquiring Dansby would make the what seems inevitable departure of Keith Bulluck a little easier to handle.  Unfortunately it will probably be lose/lose for us on that one.

It is a safe bet that 85% of the corners on that list are better than what the Titans ran out there last season.  Of course all of this is a moo point because the Titans will sign a couple of C level free agents and tell us the way to do it is to build through the draft.  While I agree with that idea, you still have to be willing to supplement your drafts with solid players, and you have to stop wasting high round draft picks.
