I can see you are very committed to your proposal R3 and I applaud you for that. As I said above, it just might be the type of competition that will replace the present Super comp if it dies with the introduction of the World League.
But just looking at the examples quoted, Sam Carter could well have lined up for the Vikings this year but probably at the expense of Darcy Swain who has shown great form and probably established himself as the most prominent of the emerging locks in the country. If not Swain, then Enever who is himself a Wallaby. Similarly, McCaffery could have and probably would have started in place of Leber or Edwards, but what the Vikings are lacking in the backrow is a No 7 fetcher. McC would handle that job better than the alternatives but is still not an out and out No 7 that is required. In the end, those changes wouldn't have made a significant difference to the Vikings outcome in the NRC.
Philip is an excellent player and would have enhanced the performance of the Rising's forwards pack, but why did he miss those games. Was it injury? Injuries will happen in all teams every year, so it is hard to make an argument that the presence of one better player would improve the performance of a team over the duration of the NRC comp.
However, I really don't have a problem with the quality of teams like the Rising or the Vikings. It is the NSW sides that I question. Even if amalgamated into one, I cannot see in the present year or in the next few to come, that there will be a huge improvement in overall quality while-ever so many of the Tahs players are missing through national duties. That might change in future, especially with a different coaching panel at the Wallabies, but if it does it will probably be at the expense of one or two of the other teams.
I am still skeptical about the makeup of the teams in your proposed competition being in any marked way different from the present day NRC teams.
