Beauden Barrett, fresh from catching an accidental boot from Springboks No 8 Duane Vermeulen in the nose and helping lead his team to an at times exhilarating victory to get his side's World Cup defence under way, believes the All Blacks have plenty more room for improvement yet.
That goes for his increasingly promising partnership with first-five Richie Mo'unga, too. The pair pulled the strings superbly at Yokohama Stadium during the 23-13 victory in front of a supportive crowd and it's worth remembering that the first time they played together was during the 16-16 draw in Wellington four tests ago.
They varied the All Blacks attack with composure and creativity – there was possibly a little too much of the latter initially – and now the whole world knows that stopping this team from winning three World Cups in a row will take some serious work and probably a bit of luck.
"It's only going to get better," Barrett, who looked fresh despite a torrid 80 minutes against the old foe, said of his partnership with Mo'unga. "I love playing with Rich, he's a super talent and hopefully for this team we can figure out how we get the best out of each other and do what's best for this team.
"We've got a lot more potential in us. It's exciting."
