Defense is about all they spend time working on so it would want to be better. In the 80s they trained less and actually spent time working on other skills.
They have over coached the juice out of the game.
Every play seemed like "heads up football" now you see HUF once or twice a game.
All this talk and thinking, thinking, thinking when all you need to do is widen the field by around 3-5m. It would change everything. I dare say if you went the full 5m you could revert back to the 5m you are so desperately seeking and it would still be an entertaining game.
But like I have said previously, if you want to remove the 6 again and still minimise the wrestle, after say 3 penalties for ruck or offside infringements by any one team, the coach of that team is to be escorted out of the ground and miss the next game as well, plus not be allowed to attend anything involving the club for that week.
I'd imagine that we would see the ruck and offside penalty go the way of the Dodo bird very quickly and the game played in the spirit it is meant to be played in.
I would pay to watch Bellamy, Robinson and Stuart in particular to be escorted out of the box by security guards. That would be one Hell of a moment.
3 penalties is an arbitrary figure. You would most probably need to tinker with it a little to see what is most feasible. But I would say 3-5 would be the correct amount.
