How to tweak my playoff roster? WHIR!

[sha]

16 team, 3 keeper, TD heavy scoring. WR's and TE's are interchangeable.

QB;e.manning, cutler
RB;turner, hillis, greene, snelling
WR/TE;r.white, wallace, edwards, branch, shiancoe
k;cundiff
d/st;patriots

want to make sure my depth is there in the playoffs, can't make anymore changes as of kickoff tomorrow. do i:
A: do nothing, I got this far with my roster....let it ride
B: Drop Shiancoe for Pettigrew. Is this a significant upgrade?
C: Drop Shiancoe for a kicker. i have a backup at every position, but how often does a kicker get hurt? scary to have one less position player?
D: Place Snelling on IR and add a kicker as well as drop Shiancoe for Pettigrew (lose my turner handcuff)

leave a link to yours. I will help asap!

IMO I would get rid of shianco. I wouldn't pick up pettigrew, not sure how he would produce without Hill. It would suck to be without a kicker but how often do they get hurt? If you don't need a te what else is out there for you to grab?

WW is pretty thin. not much out there at WR...other possibilities: Earl Bennet, Kevin Boss, Hartline?
