Four things still on McCaw's to do list?

Wallabies halfback George Gregan is number two on the wins list, with 93, although it took the former Austrailan captain 139 tests to achieve this, while English forward Jason Leonard is second with 89 wins (from 119 tests).

Number four and five on that chart are Mils Muliaina (84 wins from 100 tests) and Keven Mealamu (83 wins from 97 tests).

Indeed, the 110-test All Blacks flanker, the most capped New Zealand international of all time, could feel confident about overhauling Gregan as the most capped player in history.

The first argument would be 'if his body holds up', but it was a light footed McCaw, pounded by the Springboks in Dunedin, who was still chasing at the close of the test match over the weekend.

This lends itself to perhaps the big box that McCaw would like to tick in 2015.

No Rugby World Cup has ever been successfully defended, and if the 73-test (as captain) could achieve this, he might be able to carve out his name as arguably the greatest.

Some would argue if he hung up his boots now that mantle would already be in place.

When McCaw won the Rugby World Cup there was always a feeling it was only going to be the start of a new chapter, and he alongside the team are clearly determined to constantly honour their tag as 'World Champions'.

Mention of decline now seems irrelevent, with it barely 12 months ago that some were suggesting that Wallabies fetcher David Pocock or even Welsh captain Sam Warburton were now the foremost authorities on the deck.

Maybe as a pure ball scavenger, but McCaw has again reinvented himself, becoming a fearsome ball carrier this season.

McCaw carried the ball more than any other All Black in Dunedin, not the first time this season he has achieved this, making nearly 50 metres with eight carries, while he was the side's top tackler with 12 made, none missed.

There was plenty of hints of the arrival of McCaw, when in 2001 he won a NPC title with Canterbury (named the First Division player of the year as well as the Under-21 player of the year), before making his All Blacks debut against Ireland later that season.

A Super Rugby title and Tri-Nations would follow in 2002, as would the Bledisloe Cup in 2003, the same year McCaw was named as New Zealand's best that season.

Since then his resume reads a Rugby World Cup, three Grand Slams, seven Tri-Nations, a Lions tour whitewash, four Super Rugby trophies while he has never relinquished the Bledisloe Cup as captain.

Notching 100 test wins, if the All Blacks can remain unbeaten during the remainder of The Investec Rugby Championship could be his next goal.  Winning the maiden title of the tournament could here too.

Chasing down Gregan's record would come if he was able to lead the All Blacks into 2015, and try and become the first successful captain to defend a global crown.

And achievement number four?

Perhaps winning an Olympic Gold Medal at Rio in 2016.

It would seem absurd, but McCaw has a knack of doing things that ordinary humans might otherwise class as impossible.
