The Dolphins were by far the biggest, richest and most supported club in terms of support in the QRL and BRL respectively.
Newtown aren't that at NSW Cup level.
Even then, I think you will find the media will go "off them" as they will now finish outside the eight, and suddenly start being deemed a failure (which of course is pure rubbish)
Redcliffe was in Queensland cup which is actually lower level.
Dolphins hit ground running with ready fan base. History with beetson etc gave them legitimacy. This is what Perth are probably chasing
