Picking an argument with All Black coach Steve Hansen is usually unproductive. It's equally tough if you get on to his specialist rugby topic.
When he instigates a discussion it's done with a wry grin and one of his droll observations - tactics which are designed to provoke an unwary response. Hansen's not as agile as he was but his rugby brain is alert and seriously aligned to his vocal chords. He loves to joust and that helps maintain his edge.
It's tough to quibble with Hansen, who has directed the All Blacks to 38 wins, 2 defeats and 2 draws since he took over as supremo in 2012.
There have been flat patches but that remarkable record makes the All Blacks favourites to claim next year's Rugby World Cup. Hansen, Ian Foster and Grant Fox may find their pre-tournament task even tougher when they must cull more than 40 players to the 31 allowed in each tournament squad.
Team of the Year, Coach of the Year, Player of the Year - the honours flowed for the All Blacks after they ended their season with a 34-16 victory against Wales.
