That is one of the issues with the NRL today - its not a national competition, its more a Sydney one with other teams gradually bolted on.
Not necessarily saying its good or bad, but if it wants to be a truly national competition, 9 teams in Sydney is not going to be the way to go. Like i said, in Brisbane, the current advantage the Broncos have over the 9 Sydney teams is just not viable longer term.
It doesn't necessarily have to be a revolution though, like the original Super League proposals (where a bunch of clubs merged to form new ones), but clubs like the Tigers and Dragons, in my view, are holding the game back. This would only benefit the Dogs.
