Would you trade Cousins for Lamb or Pittman? Seeking advice please!

[Stu82 2]

I am in a deep 16 team 1/2 point PPR league.    I have Herbert as my usual #1 QB each week with Cousins and Tyrod Taylor as back-ups.   With the uncertain status of Ridley and injury to AB I am a little weak at WR.  Below is my roster with asterisks listed as my usual starters.   Right now I am in first in my division (4 league division) and pretty much a lock for the playoffs. But with that being said would you do the trade or hold off, and if so, would you do Cousins and Sutton/Gage for Cee Dee Lamb or Michael Pittman?  

 

QB- Herbert **     Cousins        Taylor

RB-  Ekeler **   

RB  Damien Harris **

Flex-  Miles Sanders ** (would probably out Lamb or Pittman as Flex if I made the trade and then flip flop between Sanders and Harris remaining weeks as the 2nd RB)

WR  Sutton ** (hopefully AB soon but who knows)

WR  Marquise Brown  **

 

Bench-  Antonio Brown, Kendrick Bourne, Shenault, Gage, (Ridley IR),   Rhamondre Stevenson, Jeff Wilson

Would you make the trade and if so for Lamb or Pittman or just hold and keep Cousins as insurance?   Thanks!!
