Lance, what exactly is your question? Are you looking at it from a team perspective, or a club perspective, or a gender perspective?
I would say the boys competition is relatively balanced. Teams and club come and go while Sturt have consistently retained the #1 position over the last ten years, the rankings and strength of the other 9 clubs have waxed and waned according to coach and player strength at the time. Getting FIFO players boosts a team in the short term, but is not an effective long term strategy for a club.
I would say the girls competition really needs a re-jig to sort it out. Girls sport is more fickle and participation is dependent on more factors than the boys. Over the last ten years the girls competition has declined in numbers and the power has been distilled, rather than been spread between clubs. The power of the boy's teams have ebbed and flowed amongst nine clubs like an ocean pounding on Sturt's lighthouse. In the girls, the competition has eroded like a iceberg with the occasional ice slip breaking away from the iceberg and slipping into the ocean never to be seen again.
