D7 is a very ordinary standard, as it would be expected being the lowest A grade division, but the competition as a whole isn't inferior to AdFL, and over the coming years Marion & OSB will find their place in the pecking order just the same as everyone else - that's the biggest upside to AdFL over SFL, is that there is a place for all clubs regardless of ability - the good ones excel up near the top, the middle range clubs sit middle divs and the battlers sit near the bottom with some good years in the lowest, and some ordinary years higher.
I do not think anyone is in debate with that. I would suggest most football people would recognize that the Adelaide Footy League is a well run organisation, and what is does works really well, but it is solely focused on Senior football and as such is not a direct comparison to our competition.
Our competition is built on maximum community involvement, and as such the integration with three grades of junior football is a key plank in what we do, this is something the Adelaide Footy League does not, and cannot provide. Saturday home games are a significant fundraiser for our clubs, something the AdFL is a long way behind us on. AdFL is a perfect fit for Lonsdale, Marion, Morphettville Park, Plympton, Mitchell Park, Edwardstown, and I expect in time Hackham. All of those clubs struggled (or would struggle now) to regularly field the required Saturday grades, and as such did not fit the expectations of our league. The Adelaide Footy League allows them to play without the expectation of a full 5 games of football and they can find their level as a result.
So yes, Div 7 is a low standard, but it has given those two clubs an opportunity to play at a competitive level, both will eventually find their level at a higher level. A couple of seasons ago they had to play against Brighton, who are now one win away from Division 1, instead they can now compete against clubs at a similar, or this year at a lower, level to them.
