"You look at the All Blacks, the majority of their tries comes from unstructured play. They are the best team in the world because they take the most opportunities. Off turnovers they are lethal.
"It's something we've been trying to create... If we can develop that side of our game and keep getting better and better, trying to get that goal of being number one in the world, we're still a long way off it, but we're working hard."
