Playoff Push-

So I’m 6-2.
I’m curious if I should try to make a trade now, and improve in a position I’m weak in. Who should I target relevant to my team? I’m pretty much willing to give up anyone, if it improves my team overall.
WR- A.Brown
WR- Aj Green
TE- Brate/Olsen
Flex-Alex Collins
Flex-Alfred Morris
Bench- Doctson, Gore, Mack, Larry Fitz, Darkwa.
