Playoff Start/Sit Advice.

First I am going to post my lineup, but leave blank the spots I need advice on filling. (12 team league)

QB:
WR: Odell Beckham Jr.
WR: Calvin Johnson
WR: Kelvin Benjamin
RB: Marshawn Lynch
RB: Jeremy Hill
TE: Larry Donnell
W/R/T (Flex):
Q/W/R/T (Flex):

So I am looking to fill those three positions. Available on my bench are:
Colin Kaepernick
Derek Anderson
Josh McCown
Colt McCoy
Mike Wallace
Giovani Bernard
LaGarrette Blount
Robert Turbin

My initial thoughts are Derek Anderson and Josh McCown. If Colt McCoy starts, I may think of slotting him in instead of McCown. My QB situation is a mess since Palmer got hurt. I don't want to start Kaep against Seattle again.

For my other flex position, I'm leaning towards Blount.

Any thoughts?

Thank you

PPR scoring? I think I only go with one QB and Wallace and either Bernard or Blount in the superflex spot. I also would lean towards McCown (yechhh).

Sorry, non-ppr.
