Again your are only using the metrics of attendance and memberships, you forget in a decade that the same few sydney teams that you want to punt, will be the juggernaut of the comp, success is cyclical and there aren't many teams that stay on top of the ladder for a long period of time, the comp was based on the inner city rivalry of the NSWRL, its Expansion teams are only as good as the opposition it comes up against, broadcasters want brisbane and they want sydney, anything in sydney....
Penrith won't be able to to hold 1st place in 2032 ten years from now, they'll be some Johnathan Thurston type player playing at the Tigers, and it will be Wests dominating, just like the Jarryd Haynes and the Lockyers, and the Slaters, the game is cyclical, the teams rotate rosters very often, to say we have too many teams in sydney is false, when AFL have the same amount, regardless of whether they want it that way or not... Cronulla has improved this year, while Roosters are falling short but look to be making finals anyway just like the sharks of 5 years ago, like i said its cyclical, and the higher you stay on the ladder, the more successful and stable your memberships/ crowds get along with more free to air games, coz you're popular.... if your tge wooden spooner like the dogs, you get Fk all free to air, which then snowballs into all areas of the clubs business... winning solves everything
