As England's caretaker, Stuart Lancaster did exactly as he was asked, and he is now reaping the considerable reward.
He repaired the damage of the World Cup, he blooded a new generation of players, and he won four matches out of five. It has proved a convincing audition.
We will learn more about Lancaster's backroom staff in the coming days, but we know that he wants to retain the assistants that worked with him in the Six Nations Championship. Graham Rowntree is a stone-cold certainty as forwards coach.
My information is that Andy Farrell can be persuaded to join England on a permanent basis too, though he will need to secure a release from his contract at Saracens.
