"There was Charlie Ngatai, touching down four times, to demonstrate his readiness for a place in New Zealand's new-look midfield," Foy wrote.
"There was fly-half Aaron Cruden with a dazzling pick-up and instinctive pass for a try, among countless examples of mesmerising skill from the hosts.
"There was full-back Damian McKenzie crossing the line twice and smiling his way through each goal-kicking routine.
"He's not the only smiling Kiwi. Steve Hansen, the world champions' head coach, is so enthused by what he is seeing that he is having second thoughts about stepping down after the Lions visit next summer. He can sense the hunger around him to extend the dynasty."
'We don't consider this to be a rebuilding phase,' said Hansen, ominously. 'We have this massive appetite to improve our game.
'We have managed to play in the past without Richie or Dan and it is time for us to find other champions. That will happen; someone will stand up. It doesn't matter who is coaching this team in 2019, they will have a shot at back-to-back-to-back (World Cup triumphs).'
Foy wrote that rugby fans should not be surprised by the form being shown by New Zealand players.
"Ambitions are sky-high because so are the standards set in New Zealand rugby from a young age.
"There is no mystery to their success, it is founded on the supreme execution of basic skills under pressure, awareness and honed instincts, allied to the geographical advantage of some tailor-made Polynesian genes.
"While the Kiwi focus is on catch and pass, a gym culture reigns in these parts. One experienced academy coach with a leading English club contacted this column to warn that skill levels among rookie English players are often 'pathetic' - leading to an abundance of 'meat-head Six Nations-type players'. He added: 'Grand Slam or not, the divide between the south and north continues to grow.'
"That scenario should be a matter of grave concern within Europe. Meanwhile, the Kiwis keep running amok; leaving the rest to chase their vapour trails."
