Steve Hansen's cautious approach with TJ Perenara is understandable and may prove to be the right path in the long run. But....and it's a but that keeps nagging away, maybe it would be better to go entirely on gut instinct on this one and say Perenara is one of those players who should be just chucked into the fray now. Why wait?
So what that he's only 20 - there's the good enough, old enough adage and more pertinently, there is the evidence being presented each week by Perenara that screams out. This kid is magical - the best No 9 in the country.
He's so raw and instinctive that opposition defences don't have a clue how to handle him. His game has multiple parts to it: he can pass, he can run, he can kick and he can pull off the impossible. He has the uninhibited confidence of youth and doesn't worry about making mistakes.
He plays with energy and spark. He's maybe a little cocky but any halfback who isn't probably isn't worth picking.
Hansen is obviously worried that at just 20 and in his first Super Rugby campaign, there is a danger Perenara could be over burdened. He's already played a lot of high intensity, physical rugby this season so far and there is a long way to go yet.
