I like both trades for you, but don't understand why you are targeting RBs and WRs instead of a QB. I think you should wait a week before looking for WR help to see how Ward gels with Big Ben and how Holmes looks with the Jet offense. I have a feeling both are going to turn into decent WR2s behind AJ. And to me it seems like you're fine at RB as well. I feel your biggest need is at the QB position.
QB - A Rodgers, E Manning
RB - A Foster, S Jackson, R Mendenhall, T Jones, R Bush
WR - G Jennings, L Fitz, S Smith (Car), P Harvin, V Jackson
TE - A Hernandez, J Tamme
