I'm also talking USA, Canada and Japan. When they're ready - and the sooner the better. The former bring additional content, the latter bring additional content and additional markets. We currently have a Rugby Championship that usually contains 12 matches played over 6 weeks (8 if you include the 2 bye weeks). If you have an 8 or 10 team competition played over an equal amount of time you'd have 24 or 30 games. That's a lot more content (relevant to more markets) from which to draw
I'd prefer a promotion-relegation model. 5 teams in the Rugby Championship (Which really confirms it as the Rugby Championship) Last place has to play a home&away fixture against the winner of the Pacific Cup. For gods sake, PLEASE include USA & Canada in this cup.
For instance: Rugby Championship: Aus, NZ, SA, Arg, Fiji
Samoa, Tonga, Japan, USA, Canada.
This makes a 10 week comp, with two byes.
Which equates to an 11 week comp for Aus & NZ with a 3rd Bledisloe test.
Too much Rugby? Gefffeeeeee
3 inbound tour matches, 9 RC matches, 3 - 4 NH tour matches.
15 - 16 tests a year (Which is actually remarkably similar to what we play now) . More rugby. More broadcast revenue. Samoa, Fiji, Canada, Tonga, Japan, ALL have a pathway to becoming and competing against the best teams in the world. (Look how far Argentina has come in 3 years of RC!)
Anyway, that's my two cents worth.
And yeah, Trans-tasman rugby comp plz. Introduce S.H. Heiniken cup since NZ are so keen to get Match experience in SA's back yard.
