3. Scrums - eliminate them. there is literally no reason to have them. if a team knocks on, why should they be given the opportunity (however slim) to get the ball back from the scrum? they shouldnt. and in this day and age, the halfback just throws the ball through a single leg thats stuck out the side of the scrum - whats the point of that? get rid of them all together.
6. Appeal system for contentious decisions. Coaches/teams can challenge decisions of Try or No Try. if their challenge is successful, the decision is overturned. if unsuccessful, the decision stands and they lose an interchange. when a team challenges a decision, a separate review board of 3 judges looks at the call and makes a decision. the referee and video referee give their opinions on the decision to this panel as to why they ruled the way they did. the panel would NOT be referees, but people that understand the game and not just the rule book.
7. Knock-ons/loose ball - far too often these days referees are blurring the lines between what is a knock-on and what is a knock-back. if a player loses the ball in a tackle, more often than not they just say it was a knock-on, when it clearly goes back lots of the time. to stop this, ANY ball that comes loose in a tackle is a 'loose ball', and is a turnover. if the ball was raked its a penalty, if not its a turnover.
10. 'Review committee' watching the entire time - the review committee (who rule on challenged decisions) should be able to rule on knock-ons and forward passes at any time. if all 3 of them agree there was a BLATANT knock-on/forward pass, they relay to the referee who halts the game. line-balls are given the benefit of the doubt to the attacking team.
11. Voluntary tackle - scrap it. seriously, why is this rule in the game? if a player gets the ball, runs up, stops and rolls the ball between his legs to a 'dummy half' positioned player without anyone even touching them, what rule did they break? they didnt knock-on, they didnt do a forward pass, theres no offside. The defense can tackle them at any time, or jump on the ball when they play it, but it should not be penalised.
13. Goal posts - adopt posts of the grid-iron nature, with the single pole holding them up being behind the dead ball line, extending over the goals to where the crossbar and uprights are.
