Rugby: More to come from Beauden Barrett as All Blacks star brings up 100 test matches

Despite having raised his All Blacks century in Sunday's 54-16 victory over Wales in Cardiff, Beauden Barrett asserts that he has more to give in the black jersey.

Barrett, 30, became the 11th All Black to reach the milestone of 100 test matches, and scored two tries to cap off a memorable occasion for himself and his family as man-of-the-match.

Since his debut in 2012, Barrett's All Blacks career has undergone many transformations.

Initially stuck behind Dan Carter in the No. 10 jersey pecking order, Barrett began as an impact player, famously coming off the bench to score the final try in the All Blacks' 2015 Rugby World Cup final victory.

Carter's retirement saw Barrett take the reins as the All Blacks' go-to No. 10, winning World Rugby's player of the year in both 2016 and 2017.

But the emergence of Richie Mo'unga forced a re-think from the All Blacks coaches, seeing Barrett shift to fullback as part of the much-maligned 'dual-playmaker' system, before returning to his preferred position at first-five earlier this year.

Speaking after the All Blacks' victory, Barrett looked back on his 100 test matches, but knows that there's still much more to come from his time in test rugby.

"It's a lot different from when I started out," Barrett says.

"I was a very raw young boy from Taranaki, who was all-out attack. I had little opportunities off the bench, a few cameos here and there. 

"But now being a more senior player in the team, and having a lot more responsibility in my life, I view the game a little bit differently.

"There's a bigger picture in life, I think I'm more conscious of that, and do things for different reasons now. My purpose is different, it's all part of growing up.

"I'm still very driven and determined. I've got plenty left in the tank."

Barrett's performance against Wales is a credit to himself, with his build-up impacted by the death of Bob Graham, the grandfather of wife Hannah.

A stalwart of the great Auckland side of the 1960s, Graham played 103 times in the blue and white hoops, and later coached the side.

Graham's passing, combined with the celebration of 100 test matches understandably saw the All Blacks star's focus shift, with Barrett describing the emotion of his week in Cardiff.

"It's been a very emotional week, and a very emotional two weeks," he adds.

"Because of the amount of support and love that's flooded into my inbox this week, those that've been there since day one. I've reminisced a fair bit this week, it brings back some great memories.

"It was hard, I didn't train that well this week, there was a lot on my mind.

"I just wanted to go out there, enjoy it and play well tonight. Enjoy the moment, because it was such a cool place to play my 100th."
