Help on who to start Ajayi,Williams, Martin or Crowell

Standard PPR scoring trying to decide between Ajayi, d Martin, k Williams, Crowell. Need one, help

Rams give away 122 rushing yards to the running backs, I would go with Ayayi this week.

Thanks, He is a homerun threat

Definitely Ajayi. Rams run D sucks as much as it pains me.
