Should I just leave it alone?

So I picked up Darren McFadden Alford Morris and I traded away Todd gurly. For Zeke Elliot what do you all think ? Keeper league we get to keep four players only paying for each player and the price goes up every player we keep.

I have Devante Freeman LeSean McCoy and Elliott And Damarco Murray Do I just hold on to all cowboy running back’s ? I have four wide receivers AJ Green Michael Thomas Chris Hogan Nelson Aguilar
