In response to 49Patriots' comment:
It's better than what the Pats marched out yesteryear....
Welker, Lloyd, Edelman, Branch and Slater < Amendola, Dobson, Edelman, Jones and Slater. Not every WR works with TB, you need to get him a smart, route savy, high motor WR or he won't work with him. Dobson is a good pick up, IMHO, I wouldn't be surprised if Troy Brown gave him the seal of approval. He'll do fine here.
I don't agree with your statement and the reason why I don't is because of the part I bolded. We know that Welker, Edelman, and Branch had a good chemistry with Brady going into camp and with the exception of Branch wearing down we knew Welker and Lloyd were durable. This year only Edelman has worked with Brady before and all of them have had injury question marks (Dobson has knee, ankle, and hip question marks in college). Potentially if everyone stays healthy AND they have chemistry with Brady I agree the WR core looks better but those are big ifs given the group and Brady's history with new WRs so for now I'd side with the known over the unknown until I see them on the field after preseason week 3
