non-PRR standard/typical scoring format

I'm going to start Marion Barber III and Clinton Portis at 2 starting RBs and Larry Fitzgerald and Marques Colston at 2 starting WRs.

Who would you recommended at RB/WR?  Calvin Johnson vs. Atl, Kevin Smith vs. Atl, Jonathan Stewart vs. SD, or Ray Rice vs. Cin (if Willis McGahee is no go)?

Megatron manos down,  i think then rice if mcgahee is a no go

If McGahee Down: Rice > CJ > Stewart > Smith

If McGahee Up: CJ > Rice > Stewart > Smith
