The connection isn't immediately obvious - but the All Blacks need Graham Henry in the Pumas camp. World rugby needs Henry in the Pumas camp and hopefully he'll make a genuine impact.
The Sanzar nations have taken a risk introducing Argentina. It was a move horribly overdue - primarily to provide the Pumas with the regular competition they so deserved, but also to breathe some life into a Tri Nations where familiarity had bred contempt.
If Argentina can settle, become serious competition for New Zealand, South Africa and Australia then the intrigue and interest rises considerably. The dynamic of southern hemisphere will change - there will be new players, new rivalries, new ideas, new parts of the world to visit.
Commercially, the Rugby Championship will have more room to grow - and more money coming in, hopefully means less players flooding out.
Then there's the wider global picture: how many teams at last year's World Cup stacked as potential winners? New Zealand and France - although even the French didn't convince for much of the tournament losing to Tonga as well as to the All Blacks in the pool round. South Africa and Australia, with some luck and ringing everything out, could have maybe sneaked the title but neither would have been considered a great side. Wales were handy but lacked belief and Ireland had the capacity to play one big game.
