Soccer runs 6 a side outdoor and indoor modified rules comps mid-week, year-round.
Cricket has indoor keeping people in the game.
I bet both sports count these players in their participation numbers.
None of the people I know who play weekend full-size soccer and cricket train twice a week on top of this, as far as i know.
Yeah true, the training commitment and load isn't as severe but that has as much to do with venue ability as anything else.
I have no clue whether soccer/cricket include shorter forms and/or indoor variations in their numbers. Either way, we can't discount the participation numbers for the true forms of those sports. The shire for example has ~150 all age male soccer teams across 16 grades with a further (approx) 50 O35 teams as well as around 30 O45 teams. 21s and 18s have their own comps as well. Last summer, cricket had around the 85 mark in terms of senior mens teams in the shire comp. Rugby league is flat out getting 16 teams together over 2 grades.
Having said that, i agree that it doesn't really matter. The vast majority of people i play soccer with or have met through the game are RL fans first and foremost and would much prefer to watch/attend RL over soccer with a good portion of them playing RL as a junior.
RL is just one of those sports that once puberty hits you find out very quickly if you are any good at the game or not and if you aren't, the discrepency in ability is tougher to hide on the field than other sports and the effect it has on your body is less palatable. In other words soccer and cricket can still be fun if you aren't good at it as can oztag and touch.
Someone brought up the NFL and i think it is a pertinent point. The philosophy over there is that if you aren't good enough for high school, college and ultimately the NFL you don't play the game at all as you may as well not bother. I wouldn't want to see as extreme a viewpoint as that here because i would hate to see park league disappear but i also don't see an issue with modest mature aged participation rates given the nature of the sport.
Junior development is another issue and we need more focus and cash there especially for coaching.
