The public who lauded Meads hardly ever saw him play, whereas McCaw lives under a high-definition microscope. We'll never know the Meads' knock-ons and missed tackles, nor how many goal kicks Don Clarke missed (a former colleague claims the conversion rate for conversions suggests quite a few.)
This is not an attempt to diminish those famous old players and their significance to people, not at all, but an effort to find terms of reference for any debate. Era by era is the best way to go. Players from around McCaw's age group, men without his responsibilities or workload, have come and long gone. Yet the McCaw mind and body remain strong. Right to the end, he charged up on defence against Argentina.
McCaw, who is 31, may struggle to maintain this level until the 2015 World Cup, but if anyone can ...
Bottom line: I've never seen a more influential footballer in any code. Along the way, McCaw has never let the game, team-mates or fans down. And if forced to pick the greatest of all All Blacks, I'd happily plump for Richie McCaw.
* Saturday night's test made another case for more indoor stadiums. Rugby is too difficult to play well in the wet for current demands.
