Big Trade: Diggs/Hopkins for my McCoy (plus other pieces)!

Hey Footclan! In need for some wisdom:

I was offered Diggs or Hopkins and either Parker or Crabtree

For my

McCoy and Benjamin/Kelley/Garçon/Pryor

Basically. It’s a 2 for 2. I receive two of his WRs and he gets one RB and a lower end WR/RB. Should I take this? Or keep my team as is?

8 team, half PPR with 3 WR slots. here’s my roster:

RB: McCoy, Hunt, Gurley, Abdullah, Mixon, Kamara and Kelley

WR: Jordy, Demaryius, Pryor, Garcon and Benjamin
