What was your point?
You spoke about a map of Melbourne and CoE for the Tigers.
I don't buy your claim that Sydney's terrain and transport system is too chaotic and disperse to have centralised stadia.
Brisbane has worse traffic than Sydney, yet I don't see anyone on here demanding we have four or five teams spread across Brisbane, Logan, Ipswich, Moreton Bay and Redlands to cover everyone so they don't get bottlenecked going into Lang Park. The Dolphins are based 34km away from Lang Park, yet they're playing most of their games there.
The only team that needs a ground of its own is Penrith.
Bulldogs and Tigers can play out of Parramatta Stadium. South Sydney, Cronulla, St George and Manly can play out of the SFS.
Sydney doesn't need any more stadia and doesn't deserve any more upgrades to suburban parks if teams won't make use of the two that were just built for them.
