Playoff moves - who to drop/pick up

Hey guys - I’m trying to position myself for playoffs and there are some tempting pickups on waivers right now (fo free). I have no room on the bench so I would have to make some. The question is, should I drop Ty Montgomery and/or Tarik Cohen to pick up any of the following

Orleans Darkwa
Robbie Anderson
Juju smith Schuster

Thanks in advance!
