Which RB do you roll with and who do you flex this week?

Which RB would you roll with: Ajayi, Petersen, K. Drake (I lean Ajayi but his usage worries me some).

Also have to flex one of these guys: Corey Coleman, Corey Davis, Crowder or Djax (could also start another RB here if you think Petersen or K. Drake is a better option)

I play Andy this week for a playoff spot so need the help!

Ajayi and Corey Davis
