Essendon great Dustin Fletcher has proposed his idea of an 18m goalsquare, which he believes, if added, could be the solution to the league's long-debated congestion issue.

The AFL has taken nine possibilities from over 80 potential rule changes, proposed by various sources.

They believe by implementing one of these rules into the game, congestion will either be stopped, or significantly eased. This way, the game will be able to free itself from too many numbers around the ball, and giant 30-man packs.

AFL chief executive Gillon McLachlan has confirmed there will be "change" by October 2018, so that each club could grasp an understanding in time for the 2019 season.

Fletcher, one of the league's best ever kick-in defenders was able to launch the ball upwards of 50 metres. In doing so, he would be able to transition defense into attack.

"The player can become more aggressive with their ball movement. As the person kicking in, it would no doubt give you more options," he told the Herald Sun.

"If you were that far up, you could be kicking it 55m-60m, hitting it almost in the centre square. Have a really good think about it, the coach would have to push his zone deeper and they might have to play a defender back inside 50."

In today's game, sides are all too often conceding a shorter kick to the pocket, then soon after, running the risk of causing a turnover by foot purely through 18 men pushing up to defend.

McLachlan last week stated he is wanting to make changes to free up the game without having to compromise the game, nor making it overly obvious for the football fan.
