Waiver/Free Agency help - Shuffling the deck

Hey guys - need some advice. 10 team half pt PPR. I’m 2-2 and looking to improve the talent on my roster/bench. Thanks!

Trying to decide if it is worth it for me to add any of these guys. I’d need to drop someone to add. Who would you drop to add? My RB play has been atrocious so far (DJ, Howard, Collins :/)

  1. Duke Johnson RB
  2. Mike Davis RB
  3. Jordan Wilkens RB
  4. Keke Coutee WR
  5. Jamison Crowder WR
  6. DJ Moore WR
  7. Robert Turbin

My team
QB - Stafford
RB - Jordan Howard
RB/WR - Alex Collins
WR - AJ Green
WR - Doug Baldwin
WR/TE - John Brown
TE - Jimmy G

BN - Marvin Jones Jr.
BN - Quincy Enunwa
BN - Keelan Cole

Bump - looking for advice.
