Adding Depth Going Forward

[patsfaninthedesert]

Here are my starters in a non-PPR league (25yds=1pt rushing/receiving, 100 yds=1pt passing, Passing TDs=4pts, no penalty for INTs)
P. Manning, A. Foster, M. Bush, Harvin, D. Thomas, J. Jones, Bowe, Bears & Akers.

I have the following on my bench: Cutler, Forte, LeShoure, Pettigrew, Britt, LaFell, Cundiff

I'm trying to add depth to my roster by shaking up my bench.
Who should be my backup going forward?
QB (pick one): Cutler, Ponder, Alex Smith, Fitz, Dalton or Palmer
WR/TE (pick two): Pettigrew, Rudolph, J. SImpson, LaFell
K: Cundiff, Tynes or should I even have a second kicker?
RB: Should I add Ryan Williams? Who do I drop?
D/ST: Falcons, Cards or do I stay with only one D/ST?

Thx.
