Smith's feat deserves praise, despite existing in the McCaw epoch. By being a centre, he has not been as prominent as his openside flanker and captain but his lieutenant's leadership, mixing cerebral with combative, cannot be underestimated.
In combination with Daniel Carter, Andrew Hore, Keven Mealamu, Ma'a Nonu, Kieran Read and Tony Woodcock, Smith is more than just a good luck charm. He is part of a veteran leadership core to whom McCaw can turn for support.
Such resources have helped the All Blacks reach the brink of equalling the record for most consecutive test wins.
If a different measure is taken among current All Blacks, Aaron Cruden reigns supreme as he has not yet played in a losing test match. There is no doubting Cruden's skill and he has also started his international career at the right time.
Any such era of performances has to be put into context. The professional age provides more test matches and, especially in World Cup pool play, easier opposition to boost winning ratios. Coaches like Sir Fred Allen and Sir Graham Henry can lift teams, oppositions can be weaker than previous eras and player records can be inflated by token appearances off the bench.
That is where records such as those of loose forward Waka Nathan (13 wins and a draw from 14 tests, 1962-67), prop Ken Gray (21 wins and a draw from 24 tests, 1963-69), centre Bill Davis (11 wins from 11 tests 1967-70), Earle Kirton (12 wins from 13 tests, 1967-70) make impressive reading.
However, those benchmarks have to be put into context when compared to players who had careers across dominant New Zealand eras such as Colin Meads (41 wins from 55 tests, 74.55 per cent, 1957-71) and Sean Fitzpatrick (74 wins from 92 tests, 80.43 per cent, 1986-97).
