No - it would be because it would involve beating all the test teams on the tour.
The home nation thing is anachchronistic though. Ireland hasnt really been a Home Nation for the last 90/100 years.
The point I was making however was that the combination of beating all five nations on the one tour would be a great grand slam achievement. And if it happened, people wouldn't be long in pointing out that it had and calling it a 5N Grand Slam.
Completely agree with your wider point, Tman.
As far as I'm concerned, the Lions tour to NZ is a waste of time.
It'd be better if they toured Argentina in my view - hopefully that happens in the near future. And would be great booster for the wider game.
