Pick up and Drop? Help Please

I am the Aaron Jones owner. AJ Dillon was dropped and available to pick up currently. I would need to drop M. Gordon or Aiyuk. Should I pick up Dillon prior to game just to handcuff in case of injury and who should I drop if so? Thanks.

We run off of waivers instead of FAAB, so there’s no way I’d get him Wednesday if Jones got hurt.

Anyone have any thought?
