Coach Todd Blackadder even had the grace to admit that just as players often thrived at the Crusaders, there were those, like Williams, that stood a better chance of blossoming outside red-and-black borders. Even in the bosom of the All Blacks, the 26-year-old league convert tended to play with a hesitancy that counteracted his natural skills.
In Hamilton, the instructions seem to be simple: don't try to be like Richie, Dan, Ma'a or anybody else you think you should be aping, just be yourself.
The result is a No 12 who is playing with a smile on his face and a Chiefs side that has over-achieved.
There was nothing phenomenal about his work against the Waratahs, just another quality performance in a midfield pairing with Richard Kahui that gives little change to the opposition.
Consistency is now allied to his game breaking.
There will still be times he gets it wrong. Those grubber kicks have an unhappy knack of cannoning straight into the opposition's legs (which fortuitously resulted in a try to Sona Taumalolo on Saturday), and he's still prone to the odd bad read on defence.
Mainly, though, he's become a damn good, week-in, week-out footy player.
And that's only going to increase the speculation around him.
But we must dash. SBW's just been seen reading a copy of L'Equipe in a cafe near the Sacre-Coeur.
*One of those is actually true.
