Milton Haig, Georgia's coach
http://www.the42.ie/georgia-seven-nations-2366222-Oct2015/“The Seven Nations, it’s certainly something that I’ve been speaking publicly about every opportunity I get,†New Zealander Haig said.
“Something like this is absolutely crucial for us because in the long run if we develop into a competitive national side consistently, that’s the kind of competition we need.
“You can see by Argentina’s progress and inclusion in the Rugby Championship how far their team has come along.
“We understand it’s a very difficult decision for the six partners to make, but I think it would grow the game globally and it would open up a big market in eastern Europe. It’s something they should consider.â€

"The more times we play tier one nations, the more comfortable us tier two nations will get. Part of the process must now be developing that side of the rugby calendar for other countries, not just the tier one nations," Bradley said.
"It's a possibility and you also have the November window as well. You've got to be realistic -- the Six Nations is a serious money-spinner for all of the home nations. The competition side of it means teams like Georgia need to play teams like Ireland, England, Wales, France, Scotland and Italy more regularly. As to where it fits in the calendar, it's up to World Rugby to try and sort that out."

“We’ve seen through this tournament, compared to other tournaments that I’ve played in, that the so-called ‘easy’ games aren’t easy any more,†he said.
“The whole standard of rugby you’ve seen in this tournament is lifted. You see teams that are capable of putting pressure on the so-called top teams, and I think everyone is excited to see that.â€

"it would be useful for us, because we always play with tier 1 nations and so we collect too few victories; and it would be useful for the other team in the play-off, because also the tier 2 teams have to play constantly with the best nations to improve" (translation, more or less)
