Saints RB's or mix of K.Smith, Redman, Stevey John?

I just picked up both the saints Rb's and with the way KC has looked on D and production out of atleast 1 of them I feel i could hit something big.
The matchups for the other arnt sexy and feel in limbo on which one of them to start at Rb and flex.

What do you think I should do here none of good options I feel
