help me set my RB/WRs--i have tons of comparable players

[two_step08]

i need to start 1 WR, 1 RB with 2 flex....its a PPR league, so that elevates welker, and some of my RBs

WR-
randy moss
welker
vjax
ginn jr.

RB-
rice
brown
portis
moreno
benson


welker and moss are questionable, so give me some scenarios of who to start if they go down...i would like to start ronnie as my mandatory RB...if everyones healthy im thinking im gonna put in moss welker and vjax...then portis is next on the list followed by rice by a hair
