As test cricket unfurled opening day chapters in Wellington and Ranchi, two batsmen converted supposition into substance.
Both have carried significant praise for their potential but had yet to convince or convert enough in the test arena.
At the Basin, conditions were up against Henry Nicholls as he moved to the wicket with NZ sent in to bat and 21 for three against the snorting inquisition of Morne Morkel, Kagisa Rabada and Vernon Philander.
Nicholls' potential had teased during his previous 12 tests with four half centuries and a recent outing against Bangladesh when he should have knocked off his maiden ton but impatiently fell two runs short.
Coach Mike Hesson and the selectors settled on the left-hander to fill the middle-order vacancy after watching his progress through the grades and measuring that output with all the other details players need to make an impact at test level. Nicholls' technique had some flaws but his temperament was strong as he showed last August in his only previous test against South Africa.
That showed as Nicholls fought through a rugged spell before lunch until the pitch settled and then played decisively to claim his first test ton and keep New Zealand in the game.
It was an innings which confirmed his potential and laid down his future challenges.
It was a similar exercise for Glenn Maxwell in India, the free-wheeling batsman dubbed the Big Show in one-day cricket but seen as the No-Show in tests.
He had an amazing array of flair in his game but struggled to distil that into consistency and the mental grind of test cricket.
He got his chance with the Aussies struggling with injury defections and a crushing second test loss.
Maxwell came to the wicket with the Aussies teetering. He shelved his impetuous instincts and alongside captain Steve Smith, toiled through the ordeal to his highest test score and a stronger recognition of his job description.
