Hey Gazza good to come up with a different approach but i am not convinced.
I reckon i have seen a post or heard some one regarding overhauling the whole scoring system.
If the ball goes thru between both goal posts its a goal. still 6 points
if the ball hits the goal post and goes past in between both goal posts or is touched by a player its a goal. still 6 points
If the ball hits the goal post or the point post and the ball goes past in between goal post and point post its a point.
If the ball hits the goal post or the the point post and the ball bounces back into play its play on just like the world game.
This would also get rid of the controversial video replay adjudication.
Another option i thought re the scoring
If the ball hits the goal post or the ball is touched by a player and goes in between both goal posts then its 3 points.
Thus still retaining the Video Review Replay making it more controversial and exciting maybe.
