I made a post elsewhere "ARU Declining thingy" about the alternate universe where existing clubs were asked to pour first grade into a new comp run in parallel with club rugby. Might level the playing field. Might not.
Saw that too.
I think there's a combination of a "put up or shut up" scenario and one which could potentially be good for setting the groundwork for the sort of club framework/competition.
Rationalise the Shute Shield. Merge or cut teams till you've got 7 left, then add a Canberra/ACTRU/SIRU/JID Cup/Whatever you want to call it side based out of Canberra. Have them run 3 Grades and 2 Colts each, with the Brumbies and Tahs players in the competition.
If that's successful (which in an ideal world, it would be) drop it down to a firsts, reserves and Colts, add four Brisbane/Queensland sides. If that continues to be successful, can the NRC, drop the reserves sides and add Melbourne amd Perth teams. If that format is commercially and financial viable, then, and ONLY then, consider dropping out of the Soup.
In the mean time, the current Shute Shield sides, regardless of whether they end up in this "new" competition, can run fully amateur teams in the Suburban competition(s), and effectively do what they want to do now (in being both grassroots and elite) just as independently run bits of the same club, rather than all under one banner.
Now, well, that's a pipedream. Who knows if there's a desire for that sort of plan, either from the clubs themselves or the ARU. Just fiddly little ideas in my head.
