Trade help: D. Adams for Mccaffery?

8-2 here looking at my play off options. In desperate need of a WR (currently have Jarvis, tate, baldwin, fitzgerald, and Godwin) and was offered Adams for C. Mccaffery (my other RBs are Gordon, Conners, Duke Johnson and L. Murray) from the #3 in our league, and my biggest competition come the playoffs. Should I do it?
