PLAYOFF WIN DEPENDS ON IT!!!

[KibblesNVicks23]

Im in a 12 team ppr league and im in the first round of my fantasy playoffs. I really need some help setting my lineup because of injuries.
Who i have starting now.
QB-Philip Rivers
RB-Arian Foster
RB-Demarco Murray
RB/WR-Frank Gore
WR-Wes Welker
WR-Brandon Marshall
TE-Jermichael Finley
D/ST- 49ers D
K-John Kasay

Bench
Miles Austin
Jeremy Maclin
Damian Williams
Kevin Walter
Jets D
Kendall Hunter
Brandon Pettigrew

Now for my question. I am deff starting arian foster but i need to start atleast one more rb and than pick between the remaining to start. So im basically asking would you roll with my lineup in now or would you substitute for big names like Maclin or the guy has hurt me all year Miles Austin.-Theyre both questionable, Austin looks like hell play.

NEED YOUR HELP PLEASE! HELP ME SET MY LINEUP!!

I like Maclin and Austin this week, but I think you have to keep the wr's you have in as well as the 3 rb's....Good luck.

Thanks for the tip. Im just struggling here because gore hasnt played well the last few games and marshall can be hit or miss. Need all the points i can get this week!
