Just thinking of a solution to the calendar issues/Super Rugby going home and away for 22 weeks.
That would be too long, or would need a break (NO!) for the June tests, so lets play them in April/May instead - straight after the 6 Nations. I think NH club seasons are done by then?
Instead of the NH teams getting together 2-3 months after they last played, why not have them come down straight after the 6 Nations and play a proper 3 test series. Ideally SA and Argentina would host a team as well, and it would be awesome if the PI's got some games too (the sides that tour Aus/NZ could do a tour of the islands after the mainland)
Mid week tests - probably not a great idea as work/family gets in the way, although State of Origin always gets sold out midweek....
or
Sunday afternoon test matches. Super Rugby keeps going throughout, so some sides lose some of their players but I think this still works as it's only 3 weeks and all teams would deal with the issue at the same time. Good test of depth and increased playing time for the extended/bench players, plus I think it evens the comp out a bit as well.
Test players go back to Super Rugby still with a month-6 weeks to go before the finals, then the RC starts after that.
Sell everything from club rugby to Super Rugby as one whole package to a broadcaster available online for streaming/live viewing, on both sides of the ditch
