Are these DL droppable?

So far this season, Charles Johnson (Car. - DE) has produced a whopping 2.5 points (Yahoo scoring), and Nick Fairley (Det. - DT) has done only slightly better at 7.5 points.  We're at the bye weeks now, so I'm wondering if these players are droppable, or if the sentiment is that they will come storming back in the future and worth stashing.  

It would help my advisement if you can provide your starting roster spots, I.E. DE, DT.....OR.....? Additionally how many bench spots you have and how many teams in your league would help as well.  I would absolutely drop both Fairley and Johnson in my league.  We start 1 DE and 1 DT.  If you do start a DT, take a look at Jonathan Hankins, DT for the Giants.  Solid 3 down DT who has shown an early ability to get pressure and nice blend of tackles.  A boom or bust DE for this week would be Kamerion Wimbley.  The Colts have allowed an inordinate amount of pressure thus far and Wimbley could be a sneaky 5 tackle/1 sack guy this week.
