I need an RB

I need to make a move for an RB2 or better. I have Brown, K Allen, G Tate, D Funchess, D Parker, C Davis and J Crowder on WR. I am happy to offload at least one of these but who should I be targeting?

I have Melvin Gordon but I am stuck with Ameer Abdullah and the 2 GB RBs. The GB situation is stinking and Abdullah is not reliable. I have made a move for McKinnon but owner not willing to let him go. Other owners are not very active with trades so not sure what to do.

Any ideas/suggestions on people I can target??
