Trade advise needed

Should I trade off Cousins or Wentz?

I’m currently 6/1 in 12/standard and all good QBs are taken. $5 WW/FA pickups so streaming a QB/DST is expensive.Regardless I need to strengthen my RB & WR situation. When will I get the highest value?

QB: Cousins, Wentz
RB:Fournette, C. Thompson, Blount, M. Mack
WR:Crabtree, Parker, D. Jackson Doct son, Pryer, M. Lee
TE: Z. Ertz
DST: Seahawks, Lions
IR: D. Johnson

I also have #1 WW priority.

I’m thankfull for any help.
