Flex-Greene,Green-Ellis or Percy

Looking for opinions here, need a win to secure playoff spot. League allows 2rb,2wr and along with a flex. I have rb- L. McCoy and Demarco Murray set and wr-Mike Wallace and Dez Bryant set. Not sure with whom to go with on the flex but leaning towards BJGE vs the Colts but Percy has been the #1 option lately and though his numbers suck Greene is probably good for 50-80 yards whereas with BJGE Billy B may just throw all game for the hell of it

I'd say ellis. he's going to get a score against the colts. Pats will be up and run the ball to kill clock if Belicheck doesn't want to be an asshole and run up the score
