Out of the running for this year... what keepers for next year?

I’m in a 12-team league (1/2 PPR), and we can keep 3 players going into next year. Long story short, my team this year is terrible, so now I’m just trying to position for next year. I’m not super happy with my roster, so I’m trying to come up with a good trade to better position myself this year. Of course, since I’ve written it off, I don’t care to trade anyone on my roster.

Given the roster below, any advice on who to keep for next year and/or who to target on other teams? I’ve already tried for Zeke, and it was a no-go.

Current roster:
QB Cousins, Dalton
WR Julio Jones
WR Brandin Cooks
WR Sanu
WR Corey Davis
WR Josh Gordon (if he ever plays again?)
RB DeMarco Murray
RB Marshawn Lynch
RB Riddick
RB KcKissic
TE Ben Watson

As of now, I’d keep Julio, Cooks, and probably DeMarco (ugh).

Any advice would be much appreciated!
