Richie McCaw played in the All Blacks' clean sweep of the Lions in 2005
Richie McCaw admits he is relieved New Zealand clinched their third consecutive Rugby Championship with a round to spare after a 34-13 victory over Argentina in La Plata.
The All Blacks touched down four times through Ben Smith, Israel Dagg, Julian Savea and TJ Perenara, with Beauden Barrett kicking 14 points before Horacio Aguila crossed for the hosts late on.
The result means New Zealand, who will host the British & Irish Lions in 2017, are guaranteed to finish first having established an unassailable six-point lead over South Africa.
And captain McCaw, who matched Sir Colin Meads' record of 133 games for the All Blacks, is confident his side will cap their Rugby Championship campaign with victory against the Springboks in Johannesburg next weekend.
"It's nice not to have to worry about bonus points or different permutations against the Springboks," he said.
"It will be a normal South African-All Blacks Test match and everything that comes with that, which is exciting. We want to go and play well and win.
"They were lovely conditions to play in and I'm really proud of the way the guys took their opportunities.
"The Pumas came to play as well and I think it was a pretty good match to watch but I'm proud of our guys because we took our chances.
"We defended really well and didn't let them over until the last minutes of the game - that shows the backbone of the team."
