I don't know it's pretty difficult to get "better" from the NFL's 4th ranked Defense in points and 2nd ranked Defense in yards.
I'd say about the only way you could screw that up is by releasing your perennial Pro Bowl RDE, in the prime of his career, just so you can make room to pay more perennial backups.
