Keeper League Trade (Murray +CJ vs Cooks +Mixon)

Was offered Brandin cooks and Joe Mixon for my Demarco Murray and CJ Anderson? standard scoring, 2 flex spots, keeper league (4 keepers). Really torn on this one. My other RBs and WRs are Zeke, Lynch, JStew, Dez, D Parker, Corey Coleman and Ted Ginn.
