Get rid of no third man up. Umpire pick up the ball and throw it up, straight away, no waiting. Boundary throw in, the same, no looking and waiting for rucks...throw it in! Do not introduce last touch over the line means a free kick to opposition....it is an oval shaped unpredictable ball...I would hate to see a kick after the siren for a win after some poor mug happened to get a fingertip on the ball before it went out. Nonsense! Do not get rid of prior opportunity. Protect ball-getter at all times. If the bloke has had a chance to get rid of it, ping him. If the ball gets knocked out in the tackle, play on.
I loved footy back in the day, I will always love footy (I think). It is different now, but there are still great marks, better kicks, incredible handballs under immense pressure, more pressure (means there are less lazy bastards playing). Trying to make the game more free-flowing with less congestion with some of the suggestions regarding zones, paying free kicks for tackles etc...may be a step too far. It is a test of attrition, the better team will eventually get the ball out and link up to score. I love the pressure and effort, the team that does it all for longer and harder, wins. Don't forget the great skills needed under the pressure and congestion. Watching that preseason square pitch stuff got a little boring very quickly. Don't change the game so much that it ever resembles that! The 60s and 70s were great...one on one contests, drop kicks, high marks, front-runners galore....but we have evolved.
