Do I have the wrong WRs

[Thor]

For my #3 WR I have

S Smith (NYG)
E Bennett ( CHI)
S Avery (STL)

so far they have been outproduced by another WR and all are available on waiver
(strangely enough though S Smith is 3rd highest scoring WR in our format, but Manningham is #1 )

Manningham
Knox
L Robinson

Do I drop any of these for any of the WW WRs ?

Mark Clayton and Meachem are also out there.
