Benjamin or Darkwa ROS?

16 team, Full PPR.
RBs: Hunt, Kamara, Darkwa, Cohen
WRs: Green, Parker, Allen, Docston, scrubs
Starting lineup: 2WR, 1RB, 2FLEX

Would you trade Orleans Darkwa for Kelvin Benjamin? I’m looking forward to playoffs and Darkwa maybe has this last good week in him? Should I sell him now and is he too much to just get Benjamin back?

Benjamin Giants schedule gets hard and they might bemch Eli soon
