Young hopefuls often hit reverse at this time of year. What had come so naturally and easily in the earlier roundssuddenly hits a blockage - pressure stuns the brain, stifles the growth and many a fledgling career has gone on hold as a result of knockout round meltdowns.
Tawera Kerr-Barlow iscertainly not buckling in these intense times. The 21-year-old, prone to a touch of the erratic and ill-advised throughout March and April, has been polished, clever and inspirational in the last few weeks, although he may have been guilty of trying too much on Friday night.
Pressure seems to be the thing he needed to drive out his best work and, in the space of four weeks, he's pushed himself from fourth to third in the All Black pecking order and there's a good argument that he's now second.
The plans that All Black coach Steve Hansen held for Kerr-Barlow may have to be fast-tracked; the conviction that the national side needs the experience of Piri Weepu in the forthcoming Rugby Championship may have to be challenged.
Weepu, fitter, livelier and in a better head space than he was even eight weeks ago, still appears to be in the human equivalent of flight mode. Maybe the version of Weepu that was unveiled at the World Cup will shortly emerge. Never one to be accused of peaking early, the 28-year-old is prone to springing to life, finding his best form when no one sees it coming.
