.5PPR/.2PPC (10-team league)

My team after losing Charles and then trading Rivers for Jennings/Matthews:

QB: Stafford
RB: S. Greene
RB: R. Matthews
WR: Fitz
WR: Jennings
WR: Welker
TE: Daniels
WR/RB: J. Nelson

Bench:
McGahee
Ingram
J. Stewart
Jacoby Jones
Sidney Rice
A. Collie

I obviously am quite shaky at RB, and no longer have a QB back-up.

I have #3 waiver priority, and there are really no great RB options. There are some pretty good WR out there, but I'm thinking I should not squander my waiver and likely have #1 next week (maybe a must-add RB will emerge???)

I am going to put in a claim for Cam Newton, but I doubt I get it.

That leaves:

E. Decker
D. Moore
D. Nelson

Assuming I don't get Cam, should I bother adding another WR? Or sit on the claim, move to #1 probably, and hope to strike gold in a week or two?

My team's gonna have a tough time making the play-offs as it is, which leads me to lean towards hanging on and hoping for a bigger impact player...

Thanks for any input.

I have Moore above your bench wrs. But you don't need any so I could see holding a week.
