"No wonder England had trouble scoring tries against the better teams at the World Cup."
He singled out Ben Foden, Chris Ashton and Delon Armitage as players who have impressed him but believes they may never reach their potential.
"A country with over a million players should be the best team in the world and England's potential in the backs is as good as it has ever been.
"But how frustrated those players must get in a white shirt.
"England and the English clubs played a game based on fear and a generation of promising backs are dying on their feet.
"That has to change."
Henry went on to describe the attitude to quick possession as a fundamental difference between the English approach to rugby and that of his homeland.
"We want quick ball in New Zealand and so we concentrate on dominating the space beyond the ball carrier. We want our supporting players to get under the opposition and to move them backwards. We flood past the ball to create good possession for our strike runners."
