Need a win to stay out of last place. Who to start at RB, PPR

I’m in 9th in a 10 team PPR by 1 game, and am playing the last place team this week.
I’ve had terrible luck with my RBs with injuries, and poor play and am reduced to
David Montgomery vs NYG
Bo Scarbrough at Washington
Derius Guice vs Detroit
Sony Michel vs Dallas
Jamaal Williams at SF
David Johnson on bye.
I currently have Montgomery and Scarbrough in my lineup.
What does everyone think?
