I'm being offered Boldin and Succop for Moss and Kasay?

Forget trading the kickers, they are just random a lot of times anyways. See if he would take Moss and Cotchery for Boldin and Holmes. If he doesn't want Cotchery, then try one of your other receivers (Harvin or Bowe) or swap one of your bench RBs for one of his that's slightly lower ranked. I would probably prefer Boldin over Moss at this point in the season, but if he has been wanting Moss for a while you might be able to get a good deal.
