Richie McCaw hasn't confirmed his retirement from rugby yet. But if he does so, then he will be one of those rare sports legends who depart on a perfect note, having just won a second consecutive World Cup.
It's a tricky business, getting the final footsteps in a team sport so right. We look at the superstars who managed it, and those who missed out.
Legends who had a bumpy departure...
Donald Bradman - cricket
Australia scored another crushing win at The Oval in London in the 1948 Ashes series, so it was not a true defeat for The Don. But in one of sport's most famous moments, Bradman was bowled for a duck needing just four runs to finish his absolutely remarkable career with a test batting average of 100. This "failure" - which left him on an average of 99-plus - is more famous than the series itself.
Colin Meads - rugby
The All Black giant was in the thick of the glorious 60s but bowed out as a losing captain against the 1971 British Lions. His stature was in no way diminished by this, and the tourists were held in such high regard - they were full of stars and played exhilarating rugby - that there is always a nice glow to the series. Meads' 55th and final test was a draw at Eden Park, leaving the Lions as 2 - 1 series winners.
