Do I dare bench Celek and TO for Davis and Walter? WHIR

[Bulard280]

Hey guys so I am in the Semis of my league and am thinking of benching TO and Brent Celek am I over-thinking this and should I just stick with what got me here? Should I start Fred Davis over Celek, normally I wouldn't bench Celek but Davis is playing the Giants who can't seem to stop any TEs. Also should I bench TO who has been on a tear and is playing the Pats secondary which has not been very good for Kevin Walter who is against the Rams. The thing that worries me is having both Andre Johnson and Kevin Walter, I am also starting Brandon Marshall.
