Drop RoJo for Willkins/Breida?

Hey Footclan,
Iam in a 10man Full PPR redraft league and right now i have Ronald Jones on my bench.
Looks like he wont be the starter for some time, if he will ever be this year, and i could grab Jorden Willkins or Matt Breida from waiver.

Other RBs on my Team:
David and Kerryon Johnson

Would you guys drop him for one of them or just sit him and wait? Or even drop another Player?

Thx for your opinions!
