Re: rule changes
I really don't like most of the rule change proposals being suggested. The semi-cynical penalty could be arrested if the referee is guided to be more forth-coming with yellow card's. Why give a warning after the fifth or sixth stupid infringement, give the warning after the second time, and then bin the player on the third. If teams know that there is a real possibility of going off the field, they will be more hesitant to lie all over the ruck, stick their hands in when they know they shouldn't be, or go after the HB when they can see quite well that he hasn't picked up the ball. These are the kind of penalties we all watch teams engage in in their own half, and we know they are doing it to stop the game.
The one rule change I do like, that I have not seen proposed on this thread is stopping the clock when a try is awarded and only restarting it when the play is restarted back at halfway. Kickers can take as much time as they need for setup and converting, and there is no gamesmanship with playing the clock. Penalties keep the same rules as before, so playing the clock is still a possibility.
