D/S/T for playoffs??? HELP

[klovell1]

My team is great and i feel i have a chance to win it all and I earned a first round bye this week. my line up is
QB Peyton Manning
QB Drew Brees
WR Demaryius Thomas
WR Randall Cobb
WR James Jones
WR Greg Jennings
RB Arian Foster
RB Doug Martin
RB MAtt Forte
RB C.J, Spiller
RB Demarco Murray
TE Owen Daniels
K Lawrence Tynes
DEF Houston Texans
DEF NE Patriots

I think i need to go with my def on the WW in the playoffs because of matchup problems and the texans have been struggling of late. The best team I like on the WW right now is the Chargers Because theyre are facing Pittsburgh my bye week, then carolina, then the jets, & raiders. I just dont like them against a hot cam newton next week... Any Advice?
