Is McCoy worth it to trade for?

I could easily trade for McCoy right now, is it worth it though? The other team would probably take Goodwin or Crowell for him. Should I pull the trigger? My WR and RBs are as follows:

RB: Gurley, Ajayi, Conner, Crowell, Johnson, and R. Freeman
WR: Green, M Thomas, Evans, Goodwin, and Gordon
