I always find it funny when people say stuff like this. Its like wen people say Sydney and Brisbane are different; Brisbane is a unified city and only needs 1 team where as Sydney is tribal and needs 9...
Its not actually based on reality, it is based on what the person WANTS to be true.
ANZ and Parra stadium can act as centralised locations for the 4 WS teams and even StGeorge, Sharks and Manly at a stretch. The issue isnt that it CANT be done, people just want it to fail....
Not based in reality, seriously?
Let's start with the basics.
1. Total land mass of Sydney is 12,400 km squared, Melbourne is 9,900km
So Sydney is 25% larger by land mass.
2. Melbourne is a far flatter city, much of it is grid based.
To give a basic example the heighest point in Melbourne is only 120m above sea level. Sydney has heaps of suburbs that are around 200m, some above.
3. Sydney has a major harbour that divides much of its north & south
Let's look at the facts in relation to footy clubs.
1. Furthest distance between two teams home bases in Sydney (brookvale to Penrith) is 62km
In Melbourne it's between Footscray & St kilda, 12km.
2. Furthest distance between a clubs home base and one of the centralised stadiums.
In Sydney it's between Penrith & parramatta- 30km
In Melbourne it's 6.6km between st kilda and Docklands
And there are plenty of other clubs a decent distance from centralised stadiums
Cronulla - to Moore park 25km (you proposed ANZ, it's even further at 30km)
Manly to Moore park 17km (you proposed ANZ - even further at 28km)

Id prefer if you told me something I said wasn't based in reality that you came with actual facts.
