DL to start?

I currently have Carlos Dunlap but am considering (and are avail) either Campbell (AZ) or Ninkovich.
Scoring is:
solo tackle - 1
TFL -1
Sack, FF, Fum Rec - 3

Dunlap always rated top 10  but wondering if either of these other guys are a significantly better play this week.

Close call, but I'd go Dunlap, Campbell then Nink( the other 2 guys are more consistent tacklers and Dunlap also solid pressure guy).
