RB help, PPR. Scarbrough? Guice? Snell?

Help me set my 2 running backs this week…
I am tied for last in a 10 team PPR league, but 9th due to points scored. I’m trying to stay out of the cellar this week. I need help with my RBs. It is now a very weak position for me. Which 2 would you start?
Benny Snell vs Cleveland
Jamaal Williams @ NYG
Sony Michel @ Houston
Scarbrough vs CHI
Derirus Guice @ Car
David Johnson vs Rams
