Engram & R Freeman for Ertz?

I was offered a trade…

I would get Evan Engram & Royce Freeman
I would lose Z Ertz

I have Herndon as my only other TE

I am good on WR (M Thomas, A Cooper, W Fuller, Juju, S Watkins) but my current RB are P Lindsay, R Jones, F Gore, and R Penny… so I need RB but is this one worth it?
