C. Davis or D. Lewis TONIGHT?

Stuck between a rock and a hard place here. I need to start one of these in the Flex (will be put as WR or RB) tonight. In a 1/2 PPR, 15 rec yd per point, 10 rush yd per point league.

I could potentially pick up Stevan Ridley and play him instead otherwise my waiver options are just as pitiful.
