Not going to go into specifics on sa footy sorry mate as it's really not my place. I am just a has-been-washed-up-hack hoping to get a kick this year.
If you like I am sure our football director (Matthew Davidson), coaches (Wayne Knowles and Ben Weekley) or President (Shane Lynch) would be happy to have a chat:

As suspected I didn't think you would have much information to share but no harm in asking. Plenty of other news going on here anyway. It does seem that Para Hills are compiling quite a list as you have mentioned and I can see your point of view on your concerns about the division being a one horse race.
I don't have years of experience with the SAAFL but going through some past results shows that they should have quite the side. With that I am unaware as to what happened with them as a club from a couple of seasons ago with them withdrawing from football.
