In most sites Greene is ranked slightly ahead of Starks. STL secondary is banged up and Rodgers should have a field day. Greene finally looked solid last week and many people will write it off as an emotional game and not to expect it this week. Their offense line was finally opening some holes and Greene was actually running with some power. I would start Greene over Starks this week but they should put up about the same numbers.
Hard to say. Greene, as was said, is finally looking a bit better. On the other hand, GB will probably be running a LOT by the end of this game, and I think Starks will do more than Grant (he can also catch better, so keep an eye on that if you are PPR).
I was all set to say Greene, but the PPR league element gives me pause. The Redskins ran all over St. Louis in week 4 and I don't expect Green Bay to have problems moving the ball in general. Starks has almost as much upside as Greene does in standard formats. I like both, but I'll give the slight edge to Starks here.
