Decisions and opinions for both men will have fluctuated as much as their thoughts have altered about the All Blacks.
Hansen thought it best for the team if the coach changed midway through a World Cup cycle but when that time came he changed course and signed on until next year's tournament in Japan.
They thought Damian McKenzie was a five-eighths and wanted him playing that role for the Chiefs but on the latest tour to Europe he was the preferred fullback against the Wallabies, England, Ireland and Italy.
Rugby works best with boundaries but the canvas must be fluid if teams want to improve.
One thing we can be sure about no matter how hard some people try and manipulate his words — Schmidt will not be the All Blacks coach.
He is a man of rare principle who wrestles with his obligations as a rugby coach and family man including the special needs of his epileptic son. Ireland have appointed Andy Farrell as his successor after the 2019 World Cup and Schmidt will move away from rugby to ponder the next move for his family.
Lions and Wales coach Warren Gatland will return to New Zealand after that tournament and wants to continue coaching but, like another expatriate, Dave Rennie, will have to get past some NZR hurdles.
The success of Canterbury, the Crusaders and the All Blacks has strengthened the powerbase of chief executive Tew and Hansen whose ideas usually find the path to success at board level. They will have talked at length about the national coaching picture beyond the next World Cup and how to refresh that landscape.
Whether Hansen wants to continue in a new role or clear out his office, Foster will be privy to that information and have assessed his plans but Gatland, Rennie, Vern Cotter, Robbie Deans, Chris Boyd, Jamie Joseph and others will be waiting for that announcement to help them prepare their next move.
