Low trade value

VI am struggling a bit with what to do with a few low value players:
Amari Cooper
Rex Burkhead
Royce Freeman

In 12 team 0.5 PPR with the following people rostered:
QB: R. Fitzpatrick
RB: M. Gordon, M. Lynch, J. Allen, A. Jones, R. Burkhead, R. Freeman
WR: D. Adams, A. Cooper, K. Cole, M. willams, J. Gordon
TE: T. Kelce, J. Reed

I would like to know some package options and potential targets. I am worried at Qb obviously. I have gone through 3 in 3 weeks and though steaming is a good strategy our waiver wire is clean due to 1 team having 4 qbs rostered. Debating trades that include a sure starter.
