Moving Chris Godwin

I’m in a 12-team PPR league. Pretty deep at WR with Godwin, Woods, Ridley, Gallup. Thin at RB. I want to move Chris Godwin for an RB. I’ve tried talking with the Mixon and Drake owners, no dice. Considering my other options and the Gurley/Montgomery owner is deep at RB with Singletary, Henry, and Dobbins. Would a 1-for-1 for Gurley/Montgomery be selling too low?
