I have said in other threads that the loss of all of Brady's targets from last year (most of the threads were Welker related) that the lack of binkies for Brady may ultimately be a good thing for this offense in a lot of ways. I think the progression of Thompkins is one of them. It is hard to think that Thompkins would be where he is right now if Welker, Amendola, Gronk, or Hernandez were on the field. Brady would have probably thrown to them much more. the lack of proven receivers on this offense has probably made Thompkins progress more in four weeks than he would have in an entire season with Welker or a healthy Gronk or Amendola.
I think by the time the Pats are at full strength (returns of Amendola, Gronk, and Vereen), this offense could be very dangerous. Thompkins (and Dobson) bring things to the table that this team hasn't had in a long time.
