As those who have run into him know, there is very little give in Ma'a Nonu which is why he has hinted at rather than outright declared his intention to pop England's Manu Tuilagi in his back pocket this Saturday.
Nonu, recognised as the world's best line-breaking midfielder, endured an awkward and forgetful 80 minutes the only time his path has crossed Tuilagi's.
That was in 2012, when England enjoyed a record victory and it was Tuilagi, only 21 at the time, who caused much of the damage.
The enduring memory for many of the All Blacks that day was of Tuilagi carving up Twickenham and then somewhat contemptuously celebrating prematurely after picking up a try-scoring intercept. He was impressively powerful, agile and alive - outplaying his vaunted midfield opponents.
Injury ruled Tuilagi out of last year's rematch so Nonu has waited patiently for this moment. It's not about exacting revenge - it's more about establishing a hierarchy and setting Tuilagi straight on a few things.
