However like Smith, who was recast as a technical expert and power behind the All Black machine for both Graham Henry and Steve Hansen, Mitchell is chaining his experience and ideas as an assistant to the England cause.
He will be front and centre of everything to do with the side's defensive and set-piece structures but won't be a regular at the top table for every pre and post-game inquisition. That's Jones' domain, while Mitchell's brief will be all about computer details, meeting room chats and on-field work.
At the 2003 World Cup, the All Blacks scored 70, 68, 91 and 53 points in their pool matches, then 29 in a quarter-final against the Springboks, but were held to 10 points as they lost their semifinal against the Wallabies.
Since, Mitchell has stayed in rugby through varied coaching and administrative duties in NZ, Australia and South Africa but whenever his duties expand there have been regular battles with authorities.
With England, his role will be specific. Sort the defence.
Mitchell will match Jones for hours on duty and attention to detail and in that odd kind of way the pair may unlock a more consistently dangerous all-round game from England.
Selection and fitness will be the base key for England's improvement before Jones and
Mitchell demand more in the November internationals and Six Nations series. The All Blacks will hope Mitchell's record continues.
In his opening stint as an assistant to Clive Woodward from 1997-2000, England never beat the All Blacks but when he took charge of the All Blacks he oversaw twin defeats at Twickenham and the Cake Tin.
