FF playoff help mainly who to play at QB

I think I know who I am going to start everywhere else but I am really struggling with who to play at QB. Tell me what you guys think. It is a PPR league for WRs and TEs only not for HBs.

QB (1)

Big Ben vs Car - You can run all over the Car D causeing less passes, but he has been consistent. Not great but solid.

Matt Cassel vs Tenn - Still coming back from having his appendix removed. Tenn ranks 26th against the pass. He has thrown for atleast 1 TD in the last 9 games he has played. I have a feeling he is going to have a big game.

Jay Cutler vs NYJ - Wildly inconsistent. Could give you a 40 point game or a 2 point game, but has been playing better of late.

RB (1)
WR (1)
Flex (2)

How I rate them:
1. Mendy vs Car
2. Roddy White vs Saints
3. Vincent Jackson vs Cin
4. Ray Rice vs Cle
5. Dwayne Bowe vs Ten
6. Wes Welker vs Buf
7. Anquin Boldin vs Cle
8. Davone Bess vs Det
9. Tim Hightower vs Dal


TE (1)
Another position I can't decide on.

Winslow vs Sea or Owen Daniels vs Den


Def (1)
This is a lock:

Steelers vs Car over Raiders vs Ind

K (1)

I only have one:

Vinatieri vs Oak


Thanks for any help.
