Who Should I Start Week 3?

I couldn’t attend the draft and have a mess of RBs that I need to decipher through for week 3… I have Cohen, Mixon, Stewart, Kamara, Riddick, Carson and Crowell to choose from. My league starts two RBs and has two flex positions… Other bench options are not great either (Hilton, Golladay)… who should I start with the 4 open slots?
