Fantasy football trade........?

I was offered Larry Fitzgerald and McGahee for Roddy White and Medenhall. Would you do it? I have MJD and Pierre Thomas as starters so Mendenhall is a back up with Donald Brown. I have Calvin Johnson, Crabtree, Kevin Walter, and Avery @ WR. I am just sick of the Roddy White inconsistency and figure I can afford Mendenhall so the RB part of the trade is a throw away to me.
