What we're essentially seeing are the same arguments being put forward in the last couple of pages that other codes had 10, 20 or 30 years ago. The adminstrators of those other codes bit the bullet and got their national competition.
There were people in Melbourne who argued against the VFL becoming the AFL, the AFL is a reality and yet the Melbourne clubs still play their VFL games, it's just at a lower level. There were people in Sydney who argued against the NSWRL becoming the ARL/NRL, same result - all those Sydney clubs still play against each other in a Sydney competition, it just sits below the NRL. Believe it or not when Newcastle and Brisbane came into the competition, people in Newcastle and Brisbane league estabishments argued against it on the basis that it would wreck the local club competitions - well, those competitions are still going. The same would have occurred at any sport that has a national league. So it's just a red herring that people put up; if the NRC moved to a two round competition, Shute Shield and it's equivalents would still go on just as those other ones that I have mentioned still do (incidentally, I find it a little ironic that the people running this line have historically belittled the Shute Shield at every opportunity, bagged Brett Papworth and some have even said that SS has and does hold back and/or sabotage rugby in Australia).
The idea that rugby can't have a home and away national league of 8 teams run during the rugby season is too ridiculous for words.
Another red herring is the super rugby argument - the games that I have watched have featured very few super rugby players, some almost none. But let's not forget that an earlier start would see super rugby players available for NRC during the June test window and then as soon as their team finished the super season, so in fact they would be available for more games than they are now or at the very least the same number.
As you've identified there a some posters here who delight in knocking every idea that anyone puts forward to improve things. Keep up the good work, it's easy to be discouraged sometimes, but you're on the right track. There's plenty of us, but often it's better to communicate and share ideas by conversations.
