WR help

[The305MiamiCanes]

I want to beef up my WR's and just wanted some insight.

Calvin Johnson
Hakeem Nicks
Santana Moss
Dez Bryant
Kenny Britt
Brandon Tate

Best options to pick up are Austin Collie, Nate Burleson, Nate Washington, Devery Henderson, Patrick Crayton, Earl Bennett, Jabar Gaffney, Antonio Bryant, Laveranues Coles

Should I stick with what I got or drop a player for one of the following?

I'd drop tate and pick up collie
