I think it's grossly unfair to only have 4 teams playing in Round 1.
Unfair on the other sides who face them the following week.
No matter how many trial games you play, there's nothing like a proper game for match fitness and blowing out the pre-season cobwebs.
I realise there's a lot of different considerations in putting together a season program. But I think all teams playing Round 1 must be a non-negotiable.
Come on SANFL, keeping the playing field level should be your highest priority.
