The elevation of Steven Luatua, Francis Saili and Charles Piutau to All Black status will, presumably, see them return to Super Rugby action later this month with greater maturity, understanding and composure.
On the intangible front, the promotion of those three improves what has been a somewhat galling statistic for the Blues.
The franchise has a strangely poor record in the production of test players. While the Crusaders, Chiefs and Hurricanes seem to spit them out, the Blues have managed to push just three men into the test arena since 2009 - Benson Stanley, Rene Ranger and Charlie Faumuina.
The failure to identify, nurture and refine local talent into the finished product had been a constant lament prior to Kirwan landing the coaching job late last year. With the country's largest playing base and a First XV schools competition that is envy of the world, it was incredulous almost that the Blues not only continually languished as a mid-table drifter, but that they continually overlooked local players who would go on to flourish elsewhere or pick individuals who showed early promise but failed to kick on.
After only a few weeks of assessing Luatua, Saili and Piutau, Kirwan could immediately see they were potential All Blacks. He knew that Ranger, capped twice in 2010, also had the potential to be rejuvenated and cajoled back to his best. He's also hopeful that Frank Halai, left out this time having made the wider training squad, will earn promotion later this year.
"Frankie is the dark horse for me," says Kirwan. "He's been very, very solid. Francis is just hugely talented and he's going to go a long way. Charles is another X-Factor player for us, as is Steven Luatua.
"We need to make sure we keep developing these young guys. They are really disappointed with the performance [the 38-28 loss to the Highlanders]. They have to make sure they learn about consistency of performance and that it is a grind. We probably have not done well in the grind but they will learn that and the more exposure they can get to international football, the better they will be for us."
