Hurricanes head coach Chris Boyd is keeping two-try hero Vaea Fifita grounded after his impressive showing against the Blues on Saturday.
Fifita, who can also play in the back row, crossed for a second-half brace at Westpac Stadium as the 'Canes closed in on the Crusaders.
But despite his excellent performance with ball in hand, Boyd is demanding more from the 24-year-old in his defensive game in the future.
"He had a good offensive game scoring two tries, and I don't think he had the greatest defensive game," he told Stuff after the 'Canes stayed in touch at the summit.
"He's a spooky athlete and you could probably play him on the wing. For a man of that size to have that sort of athleticism is great and there's a lot more upside for him to come yet.
"He's learning the game in terms of his role and where he needs to be. He needs to up his physicality in certain situations so he's not the complete package. But in terms of raw potential he's got plenty."
Hurricanes scrum-half TJ Perenara, however, was full of praise for the second-row and feels he can feed Fifita for more tries when possible.
"We saw it out here before he played Super Rugby, the stuff he did at pre-season training, even club rugby, he's a good player and if we can get him in position where he can express himself then that's good for us," he said.
"You see his pace and he's hard to stop. There's a lot of players around the league who fit that same mould but it's nice to have one of them on my team."
