Need some help...week 14..WHIR (I'll give it my best shot)

[Drifter]

First week of playoffs and I have a lotta choices.

QB-Warner/Rothelisberger (leaning warner though)

2 WR spots and 3 WR/RB spots for these guys

WR Driver vs CHI
WR Mason vs DET
RB Jacobs vs PHI
WR Meachem vs ATL
RB Maroney vs CAR
RB Stewart vs NE
RB Bradshaw vs PHI
WR Roy Williams vs SD
RB Benson vs MIN

9 guys for 5 spots and I don't know who to start. I know for sure I'll probably pick the wrong ones. Help me out please and thank you!
