He's only 20 and not a full member of the Blues squad. Inevitably he'll make mistakes and his skills will come up short at times. What matters is that each time he plays, he shows some quantifiable evidence that he's processed his previous performance and is not repeating mistakes.
That was the strength of his performance on Friday - he kicked out of hand better, chose his times to do it and had a good handle on his decision-making.
"I had my moments," said Hickey. "There was some good stuff, and some stuff that I would change. In the second half we took control a little bit and toughed out a win.
"It is tough [playing Super Rugby] but as you play more games you become more comfortable with it and I think it is just about learning from your errors. In Canberra, I certainly had a lot of learning. I was trying to take those [lessons] and make amends I guess. The next time you get to play you have to show you have learned. We talk a lot about things that have happened and what I have to work on."
The other quality Hickey has to offer is a level head. This last week he has been restored to the Blues No10 jersey and named as captain of the New Zealand under-20s. Yet there was no euphoric sense of him being blown away by it all. He says he's not a long-term thinker but a week-to-week man and his goals extend no further than delivering a better performance than his last.
