The first option is clearly a showcase option, its akin to some of the rules in the NFL pro bowl in essence and isnt ever going to be introduced to the real game. This game is a bit of fun, its supposed to be fun and this rule is a bit of fun. Lets not take it too seriously.
The second rule is a bit of an issue, could be a godsend to the game, could be terrible. The PTB is a mess right now with the massive advantage of a penalty and 6 more tackles given sometimes, and nothing at all given for some very very similar play. If this lesser punishment gives refs the advantage of being able to punish laying on and slowing down at the PTB more readily then it would be a good thing. I dont really have a problem with defending teams 'tactically' holding down and seeing the tackle count reset. A clever player would use it wisely and i think that would an extra dimension to defensive play.
The downside is the possibility that every infringement wont be punished, which means that all this change will do is encourage more laying on and slowing down at the ptb, more hands in at the ruck (which the refereeing of in the four nations was pathetic) and more messing about, because the player knows he isnt likely to be punished and even if he is the punishment is lesser.
Its a decent idea but it needs to be refereed well
Number 3 seems a logical extension of existing rules. the 40/20 is a great success, the 20/40 is the logical extension of it, it doesnt punish great defence any more than a fantastic offload punishes great defence. Kicking those kicks is difficult and it is up to the defence to stop them, great defence should stop them. Saying that, i think the advantage would be too much if it was allowed on the last.
A couple of rules i would like to see trailed would be: High tackle is an automatic 5min sin bin. 'On report' means looked at by the VR and punishment handed down immediately, and play the game in four quarters of 20 mins.
