"Like Eales, McCaw epitomised what rugby is all about, as a person and a player who did more for the game than the game did for itself."
The selection time frame starts with the advent of professional rugby in 1996.
Ella was a dazzling No 10 who led the Wallabies to a Grand Slam victory in 1984, scoring a try in all four tests against England, Wales, Scotland and Ireland, before stunning the game by retiring that year, at 25. Ella admitted there were close calls in other positions, such as opting for Australian Phil Kearns at hooker over Dane Coles, and didn't mention Kearns' fierce rival Sean Fitzpatrick.
Splitting Dan Carter and Stephen Larkham as first five-eighth was another area of serious head-scratching.
"Although Larkham could be freakish at times, reading the game and finding holes in the defensive line better than anyone else, Carter's longevity in the position and his consistency as a leader make it hard to argue against," Ella wrote.
"Carter and Larkham are absolute champions of the game who certainly deserved to be acknowledged for their abilities to turn a game around and for the entertainment that they provided to all the fans in Australia and across the ditch."
Ella's XV: Christian Cullen (NZ), Joe Roff (Australia), Tana Umaga (NZ), Jonah Lomu (NZ), Tim Horan (Australia), Dan Carter (NZ), George Gregan (Australia), Toutai Kefu (Australia), Richie McCaw (NZ), Jerome Kaino (NZ), John Eales (c, Australia), Brodie Retallick (NZ), Carl Hayman (NZ), Phil Kearns (Australia), Tony Woodcock (NZ).
