Please HELP ME during the playoffs!!!

[Indopunk]

I'm in the playoffs in the two leagues I'm in.

Should I start Calvin Johnson (DET) vs. OAK or Demaryus Thomas (DEN) vs. NE? I got burned by Megatron last week and can't afford to lose now. I know I should "always start my studs" but I have my doubts about him.

Which D/ST should I start? CIN @ Rams or SEA @ Bears? SEA has been good to me lately but CIN vs. Rams looks tempting.

In my other league, should I bench Aaron Rodgers and start Matt Ryan (ATL) vs. JAC? I got burned last week in this week when they benched Rodgers and I'm worried this will happen again.

Also in this second league, which of these four WRs should be my starting three? Welker, Jordy Nelson, Laurent Robinson, or Dwayne Bowe?

Answer mine and I'll answer yours.
