As I said, spoken like someone whose side can't win a GF.
This is Australia, not Europe.
The champions are the side that win the grand final.
Do you value a NRL Minor Premiership more than a Grand Final win?
And? This is soccer- the exact same sport they play in Europe with the same rules.
In League, a GF is valid because it is much easier to score points in League. All you need to do is cross the try-line from any side of the field and ground the ball. Most times in League, the better team wins, hence in most cases the best team wins the GF. In 100 years of League there has only ever been one 0-0 draw.
To score a point in soccer (football), you not only have to strike the ball within the vicinity of the goal mouth, but you must also get it past the opposition goal-keeper. Many times the better team doesn't win a game. Are you going to suggest that Liverpool are a no better team than Stoke this season, or the same about Chel$ki and Fulham? In this past year alone I have seen 4 or 5 0-0 draws in the EPL.
The governing bodies of the major soccer leagues the world over realised long ago how difficult it is to score in the game, and recognised that in a domestic season, the only way you can judge who is the best team is by counting all the results and awarding it to whoever finishes on top. Soccer Grand Finals have only existed in Australia since 1978 as a way of generating more revenue for the game and to make the competition easier to understand for bogans who call soccer "soccer".
Mariners are officially recognised as the best team in 2007-08. And unlike their northern rivals, they are still well in contention to add another Premiership trophy (and maybe a Grand Final one too?) to their trophy cabinet this season.
