Watching a NAB Cup game for the first time in a few seasons I took great note of the newly-trialled rules.
I think the nine-point "Super Goal" is eventually going to be introduced to the Premiership season, and I'd be very happy to see it.
I mean, it (kicking a nine point goal instead to a six point goal) becomes tactical, in that players in a tight contest may be able to go for a more difficult shot to get nine points, as opposed to setting up an easier though less rewarding six point goal.
The rule where it is "play on" when the ball strikes the goal/behind posts, and remains in play is an interesting one, though it seemed like the players all seemed to stop and start when they realised the ball was still in play. It may be that they just need to get used to the inception of the rule, but it is another new rule that could liven up the game and make it a bit more interesting.
