AFL Final Ten Wildcard Edit Disrupts Level Playing Field

The AFL has made a significant change this season by introducing a ‘Final Ten’ format. This new system includes a wildcard round, which expands the traditional Final Eight model. This adjustment has sparked debate regarding its impact on competitive balance within the league.

Overview of the Traditional Final Eight

The Final Eight format has been the standard in the AFL since 2000. Here’s a brief outline of how this system works:

• Week 1:
  • Match 1: 1 vs. 4
  • Match 2: 2 vs. 3
  • Match 3: 5 vs. 8
  • Match 4: 6 vs. 7
• Week 2:
  • Match 5: Loser of Match 1 vs. Winner of Match 3
  • Match 6: Loser of Match 2 vs. Winner of Match 4
• Week 3:
  • Match 7: Winner of Match 1 vs. Winner of Match 6
  • Match 8: Winner of Match 2 vs. Winner of Match 5
• Week 4: Grand Final: Winner of Match 7 vs. Winner of Match 8

Probability Analysis of Winning the Premiership

The assessment of premiership chances provides insight into the effectiveness of the finals format. Assuming each match is a 50:50 contest, the winning probabilities vary based on the team’s progression. For example:

Teams 1 to 4

• Path 1: Win Week 1, Week 3, and Week 4 results in a 12.5% chance.
• Path 2: Lose Week 1, win Weeks 2, 3, and 4 results in a 6.25% chance.

This leads to a total probability of 18.75% for teams 1 to 4.

Teams 5 to 8

• Only one possible path for these teams: Win all finals, resulting in a 6.25% probability.

Introducing the Wildcard Round

With the new ‘Final Ten’ structure, the wildcard round will see teams ranked 7 to 10 face off. This setup aims to determine final positions within the traditional Final Eight format, thus creating more opportunities for competition. However, it raises questions about whether this change enhances fairness.

Evaluation of the Wildcard System

Statistical analysis shows that for teams 7 and 8, the probability of winning the premiership decreases from 6.25% to 3.125%. This reduction diminishes their competitive viability compared to the previous Final Eight setup.

The Case for the ‘Two-Conference’ Final Ten Model

An alternative proposal suggests a ‘two-conference’ Final Ten model. This system would allow for two conferences of five teams each, improving on the traditional layout by distributing probabilities more effectively. Here’s how the two-conference setup could work:

• More finals would be played, with greater engagement for teams throughout the season.
• It enhances competitive balance, rewarding higher-ranked teams.
• The design underlines the value of a structured tournament format.

Unlike the wildcard round, this configuration would not penalize lower-ranked teams as severely.

Conclusion

While the new wildcard round introduces novelty to the AFL, this change may come at the cost of competitive balance. A two-conference Finals model could provide a more balanced solution that rewards performance and engagement. Ultimately, it’s crucial for the AFL to weigh commercial benefits against competition integrity.
