Is it fair that a successful club like Sydney gets all these advantages after recently winning a premiership?
That game can be played all day but how exactly does Sydney suffer? They generally don't lose players they want to keep, at least compared to the normal rate of movement, that have proven to be able to attract the most elite talent, recent success, financially strong. What part of the ledger needs to be balanced?
I keep going back to Sydney because you stated 'the northern clubs'. I have no issue with GWS and GCS getting something significant.
The academies are about growing the game across the whole of the northern states. If you only let GC & GWS have them, and not Sydney or Brisbane, who looks after the areas not covered by the first two? Heaney came from Newcastle - not a GWS area. So who puts the development into these areas? The VFL/AFL haven't bothered for a hundred years. We come along and put the effort in and start producing results.
But all four clubs need to work at this to grow the game, not just the newbies.
