Need some roster update advice!

Looking at mainly upgrading WR wanted to see what you guys thought. QBs I’ll be streaming when needed, TE is a bit shit. People started drafting 2 TE while I had the long wait to draft… full PPR, right now team is
Q: Jackson
RB: Kamara, Gurley, Sony, breida
WR: Evans, Lockett, Westbrook, Watkins, Miller
TE: Rudolph

I would trade Gurley and Watkins, two risky guys… for a better WR or RB
