My 12 team league runs only 2 RBs and no "utility" player.

I have Stephen Davis who is now out.

My 2 backup running backs are Lamar Gordon and Onterrio Smith. I currently have Smith starting because Moe Williams probably won't play and Smith will get the majority of the snaps and can catch the ball out of the backfield.

The only thing I'm worried about is Minnesota is playing against a pretty good D in Philly, and Gordon is playing my Bengals horrible rush defense.

Portis is my RB1, not that that should really matter.

What would you do?
