I agree that the Minor Premiership should have more status, maybe some extra dollars and a trophy to whoever wins it. If you scrapped finals altogether, you'd see attendances starting to drop off now as the title would effectively be in the bag for the Broncos. It happens in the EPL, mainly for those teams mid table, but the difference there is that they have Champions League and UEFA Cup qualification and the relegation battle to keep things interesting. We've got a totally different competition.
I see nothing wrong with an 8 team finals series in a 16 team competition and I agree with a few posters here that the AFL finals system makes a lot more sense. Either that or split the competition into 2 conferences, ala American football. In a 16 team competition, you'd have the teams who finished 1st, 3rd, 5th etc in one conference and 2nd, 4th, 6th etc in the other. During the regular season, each team plays the team in their own conference twice and the other teams once (22 rounds).
For the finals, you could have two different approaches. In each conference, 1 plays 4 and 2 plays 3; the losers are eliminated. Thw two winners play off for conference champion and then the two conference winners play off for the Premiership, much like the way the Superbowl works. We currently have 9 finals matches, this system would reduce that by 2 to 7 matches and is therefore potentially flawed.
The alternative, would have 1 play 2, and 3 play 4. The loser of the 3 v 4 match is elminated. The winner of the 1 v 2 has a week's break and goes to the conference final, the loser plays the winner of 3 v 4 and the winner of this match goes to the conference final. Results in 9 matches again, the same as what we have now.
With the reduced number of rounds, you could have a complete break when the SOO series is on, perhaps introducing a knockout type competition over the same period. Something similar to the old Amco Cup. Either a straight knock out or have 4 groups of 4 teams who play each other, the winners of each group then proceeding to a knock out stage. Have all these matches played in regional areas.
