Mixon for a QB/WR?

10 Team standard. So I was offer a QB(Wentz, Cousins or Watson) and a WR for Mixon. His WR’s are Ridley, Davis, Thielen, Jeffery & Baldwin. I been okay at streaming QB’s they been serviceable my WR core is pretty weak. Should I try for one of those QB’s and aim for Jeffery or Ridley? I want to keep Mixon myself just not sure cause I suck at trading .

My roster is

QB: Stream

WR: Tyreek Hill, Mike Williams, Tyler Boyd, Allen Robinson, Coutree, Dede Westbrooke

RB: Kamara, Zeke, Mixon & Derrick henry.

TE: Kittle/Rudolph

Kicker Lutz

D/ST Stream

I’m 3-1 with the 2nd PF by a decent margin so idk if I should make any moves at all right now
