The modern rugby player has all sorts of impressive functions and features but the hardware still operates best when fed the most simple instructions. What it comes down to for every player - All Blacks most definitely included - is being sent into battle with concise, clear, simple objectives.
Whatever else has or has not happened at the Blues in the past decade, the one consistent failing has been a disconnection between players and coach and an inability of the latter to spell out exactly what it is he wants.
Umaga is articulate but not elaborate, giving him the necessary flexibility to communicate as effectively with his players as he can the board, media, fans and sponsors.
Umaga knows the importance of clarity and, equally, he gave every impression at his unveiling that he knows the value of preparation, research and analysis.
He talked of the region's enormous talent base and its potential but also warned against the dangers of believing talent alone could win games and titles.
His take from afar has been that the players, or majority of, did not lack a work ethic this year - they lacked direction and understanding of their individual roles and how they fitted into the collective.
In his time with Counties, Umaga has shown he can not only explain his game plan, but that there is sophistication to his strategic thinking.
Perhaps what should be of most satisfaction and comfort to the region's rugby followers is that Umaga had no interest in making grand statements. His only promise was that he would give all he has got and that despite his long association with Wellington and the Hurricanes, Auckland has been his home for the past five years and is where he and his family want to be.
A hallmark of the Umaga reign might be under promising and over delivering - which would be a most welcome change.
