Is this a good trade? Dj Chark for Juju

So my team has super under performed even though I sit at 4-3 (I’ve already lost Week 7)
I have Juju Smith Schuster and I was offered Juju, Singletary, and Latavius Murray for DJ Chark, Duke Johnson, and Darrell Williams. Is that a good trade?
My other receivers are Davante Adams (hurt), Larry Fitzgerald, and Auden Tate
My other running backs are Fournette, Kerryon, and Devonta Freeman
So is that a good trade for me or not?

I like Chark over JuJu but I heard something this morning about Kamara has a possibility of not coming back this season. It may have just been a rumor but I’d look at that first before I deal Murray
