Antoine Winfield & James Farrior
 

2 solid IDP's also available.

Winfield was the #7 DB in the league last year, he's currently making 390. He can be extended to 540.

Farrior was #25 at LB in a down year for him, but makes a reasonable 635. He'd be 785 on a renegotiation.

Both are available cheap, though Winfield is in the running for my 3rd RFA tag if I move Branch.
