Another week I'd like your advice

Scoring is 1 pt for passes defensed and assisted tackles, 2 pts for tackles, 3 pts for sack, FR, INT and FF and of course 6 for TD.
We play one DL and two any D and have room for one D or maybe 2 if I want to drop my reserve QB.

This week,  I've got JPP& Barnett who are on byes.  I've got DJ williams & Sean Lee.  Available DL: Peppers, VandenBosch, M. Bennett, Mincey & Andre Carter.  Available any D: Landry Laurinaitis & Farrior.
1. Is it worth stashing JPP & barnett on my bench, or should I drop Barnett?  (JPP has done well, so I don't see any reason to drop him)
2. Hang on to Williams & Lee or trade for any of the availables?

Thanks for your help

I'd drop Barnett and pick up Laurinaitis if you need to make a move. Otherwise, stay put.
