Add St George to that mix. All games between those 4 clubs should be played at SFS going forward. That's 12 games every season if the all play each other twice.
The extra 3 games at SFS would give roosters/souths more scope to take lower drawing games away to other places whilst still giving sydney fans a full slate at SFS.
Exactly!
I was looking at a map the other night and realised the success of the AFLol comes from the fact that every team is a first-ring suburb bar Essendon.
That's why when Collingwood v Carlton v Richmond v Essendon v Hawthorn games always get big numbers, they market the inner-city rivalries well...even North Melbourne used to get big crowds before they became the Wests Tigers of the AFL.
Whilst Sydney is more spread and divided by water, and some of or original tight-knit to the CBD clubs like Glebe, Annandale and Newtown are gone, we have four of our nine Sydney clubs as remaining first-ring suburbs: Easts, Souths, Wests and St George Illawarra (just)
Norths would be another, as would Newtown, wnich is important as if they were to return as Perth and Adelaide respectively, we could turn them into our versions of Swans and Lions, where their huge historic bases will attend away games in Sydney as those AFL clubs' fans do in Melbourne. Norths obviously a lot more likely to return.
All of these teams should battle roughly every second Friday at the SFS. Make it a tradition and well-known.
Below example for when the teams are all not complete rubbish like half are atm
E.g.
R1 Easts v Wests (25-28k)
R3 Souths v Easts (30-35k)
R5 Wests v St George (25-28k)
R7 Souths v St George (25-28k)
ANZAC Day Easts v St George (40k+)
R11 Souths v Wests (20-25k)
----Don't waste big games in Origin---
R18 Easts v Wests (25-28k)
R20 Souths v Wests (25-28k)
R22 Souths v St George (28-30k)
R24 Wests v St George (28-30k)
R26 Easts v St George (30-35k)
R27 Souths v Easts (35-40k)
Then the Western Sydney cluster of clubs can do the same across their stadia:
R1 Penrith v Parra (25-28k) Commbank
R3 Canterbury v Parra (30-35k) Accor
R5 Penrith v Canterbury (20-22k) Penrith
R7 Wests v Parra (25-28k) Accor
R9 Wests v Canterbury (20-25k) Accor
R12 Wests v Penrith (18-20k) Campbelltown
----Don't waste big games in Origin---
R18 Penrith v Parra (20-22k) Penrith
R20 Parra v Canterbury (28-30k) Commbank
R22 Canterbury v Penrith (20-25k) Accor
R24 Parra v Wests (25-28k) Commbank
R26 Penrith v Wests (18-20k) Penrith
R27 Canterbury v Wests (25-30k) Accor
Finally, for the outliers Cronulla and Manly, the NRL needs to hype up the Battle of the Beaches so it doesn't get 10k on a Sunday afternoon, and there we go, big crowds are on their way...
Will the NRL do it...no way!!!
