Start/Sit/Trade RB Question please advise?

So my running back are currently.

Devonta Freeman
Jay Ajayi
Lamar Miller
Alvin Kamara
Aaron Jones

I am thinking of starting Freeman and Miller as RB 1 and 2 and flexing Aaron Jones.

Don’t think Ajay is startable anymore until he shows something and trading him right now will get me nothing of value. However, Kamara is so consistent. Which 3 RB’s would you start if you really need a win for week 9.
