"He's a young player who had success last year and he's come back and he's trying to be the ultimate professional and he's probably trying too hard. He's looking to do everything rather than concentrating on the things that he does well."
The tough times endured by Smith, Joseph and the Highlanders seem a world away months after they comprehensively beat the Hurricanes to win their first championship. It might be tempting for Smith to forget them, but if he is to shine at the World Cup he would do well to keep them in mind.
Because there have been signs this year during his three tests for the All Blacks that he is again trying too much. He was fired up before his first assignment of the season against South Africa in Johannesburg when he said he was effectively seeking revenge for the defeat the year before, and he had what was generally considered his worst game in black next time out in the defeat to Australia, a test in which he was sinbinned for a high tackle. There was too much haste, not enough speed.
The 26-year-old was better a week later in the All Blacks' demolition job against the Wallabies, but his style of game prefers front-foot ball, and his team got that at Eden Park.
Joseph said after Smith confirmed he had signed with NZR until 2019: "Since I have known Aaron, he has blossomed into one of the best halfbacks I have seen. In a sense he is redefining the halfback role by the way he plays, and you know players like that don't come along that often."
Smith's pace and fitness mean he can get to more breakdowns than just about any other player. Together with his pass, he is redefining the No9's role, as Joseph said.
But while his job description at the Highlanders consists of playmaker and strategist as well as his core roles, Smith should pare it down again for the All Blacks ahead of the World Cup. Then his year could get even better.
