I would go to 20 teams maximum. Tasmania is a no-brainer. The 20th team is from Adelaide - merging two very popular SANFL clubs in Norwood and Sturt. A lot of currently disenchanted Crows fans would revert to these SANFL teams that they followed before the birth of the Crows. Spilt the AFL Comp into 2 divisions of 10 teams each with promotion and relegation of 4 teams each way annually. Each Div has 18 round minor round season with top 6 teams playing in respective finals series. Div 1 Grand Final remains on Sat Arvo at the MCG. Div 2 would become the Sat night GF played at the highest ranked team's home ground - played on the week before the Div 1 GF. Div 2 gets its own "Brownlow" - it would be the Adam Goodes Medal.
