Ideally you play each other twice. Compromise is two divisions of nine teams. Home and away against your division. Play all teams in the other division once = 25 games.
Start season mid March end early October. Pre season is currently too long. Players get a break till end of year, return January.
Cut quarters to 18 minutes plus time on.
Eastern Division : Tiges, Collingwood, St Kilda, Hawthorn, Carlton, Swans, GWS, Brisbane, GC
Western Division: North Melbourne, Essendon, Melbourne, Bulldogs, Geelong, WC, Freo. Adelaide, Port.
Finals roughly the same format with the Division finals being the current preliminary finals.
More silverware on offer. Grand final - champs from two divisions.
Pre season 3 out of every 4 years Eastern v Western Division All star games. All Australian team chosen from those squads.
Every 4th year a preseason State or Origin carnival, knockout based on seedings. All Australian chosen from best players.
Fixture would be fair. Every Victorian team would have 6 interstate trips each year. Each interstate team has their two derbies.
On occassions one division will be much stronger than the other but if you cant make top 4 out of 9 teams you cant complain about missing out on a chance for the flag.
Now someone just has to fix up the umpiring. ;D
