The All Black selectors have sifted through a stack of talent since the 2007 World Cup.
A number have not been All Blacks for much time at all, such as John Schwalger, Kevin O'Neill, Bryn Evans, Lelia Masaga, Tamati Ellison, Mike Delany, Benson Stanley, George Whitelock, Jamie Mackintosh, Alby Mathewson and Hika Elliot.
There were some picked for a tour, some named but unable to train because of injury and others called into training camps.
Flanker Scott Waldrom went on the 2008 tour and made his solitary appearance in the six-game trip against Munster. The next year he suffered a back injury.
Some, like Ben Franks at the start of his career, Brendon Leonard and Chris Masoe towards the end of theirs, were announced in squads but got no further because of injury.
