I was offered Roddy White for Darren Mcfadden straight up.

My other backs are Hillis, MJD and Ryan Mathews. Other WRs are Jennings, Boldin, Fitzgerald and Lee Evans.

I'd like to keep Mcfadden, I'm pretty sure I'm going to turn it down. How much of an upgrade is White over my WRs? I'm thinking about countering with one of Jennings/Boldin/Fitz and Hillis for White but I'm thinking that I would be giving up too much.
