I think there is some truth in what the OP is suggesting. Although SOO is a marquee showcase event for the game (very important, and marketable outside NSW and Qld) by its very nature it confirms that in real terms rugby league is a game from 2 states (at least in the perception of those who know it no deeper than that). So it is a bit of a wonderful strength, but in some terms a weakness (in expansion/relevance to other states/markets etc). Of course it is one of the major highlights, if not the highlight of the league season (I wonder if sometimes it seems to those outside of club interest/affiliation, i.e. casual SOO watchers from states outside NSW/Qld, that SOO is of greater importance than the NRL premiership). I think particularly in Melbourne, that is slowly building a league culture, the point is always confirmed come SOO time when the Storm's "home town" boys run around for Qld and NSW. Not sure it's a situation that can easily/readily/quickly change.
