Who cares? It would have been a shit stadium then and no one would want to go to it.
You can't compare Aussie/Sydney to USA for sports especially footy. They are a beast of a Country with one City teams and have no other football rivals of any significance and an uninterrupted history to build and continue an unchangeable market dominance in both ratings and attendance success.
We on the other hand have had at least 70 years of failed, at times corrupt and crappy game administrators in a market place full of significant rivals. Just when we started to get the upper hand in the mid 90's a civil war erupted that ruined that dominance and success and ever since never allowed us to get back to capturing the public's imagination in the same way.
We are now a splinted lot in Sydney in particular and the youngest generation are less and less interested in sport as a whole. So if you don't build it right, good luck in filling it up consistently.
