Fantasy Football help please =)

Ok heres my dilemma this week I play the number on in my league, Im 1 game behind a win would be huge. I have no need to change my QB, K, or DEF as my QB is aaron rodgers and my other kicker and DEF are on bye weeks. My leagues scoring is as follows.
RB's - 6 points per touchdown and 6 points for 80 yards rushing
WR's - Same as above except with receiving yards

This is what I have now
Starting RB's - MJD, and James Starks....Benched RB's - Peyton Hillis and Marshawn Lynch (I have to start at least 2 and at most 3)

Starting WR's - Pierre Garcon, Victor Cruz, and Jordy Nelson.....Benched WR's - Gronkowski is my only option because Dwayne Bowe is on a bye.

So pretty much my question is should I start Gronkowski (who is seeing a great decline is receptions on account of the return of hernadez) over Jordy Nelson, Get rid of nelson to start another RB, or do the first option and change out starks for another RB. Like I said its a big week and I never ask for advice as Ive been in this league for 2 years and won the superbowl each year, but this is a big game that I really cant afford to lose. Plus a win would give me head-to-head just incase we are tied at end of season. If you could PM that would be better because Ill prolly lose this thread after tonight because of everyone else posting.

 

Keep Nelson in, he should have a big game against the Rams.

 

you think?.....what about the RB situation, do you think starks will also have a good game? or should i put int hillis or lynch instead?

 

Sent you a pm, but you never know if the Pack are going to just dominate the Rams with the passing game, which most likely could happen, or decide to give the ball off to Starks. Hillis and Lynch are a tough decision since they aren't on very good teams.

 

Put in Marshawn Lynch, take out Starks. Keep the WR's.
