Turning to why Martin Johnson's new-look England are struggling, McCaw added: "I suppose you could argue that England may be more vulnerable when the pressure comes because they don't have the experienced guys like Lawrence Dallaglio and Neil Back in the team but they are all pretty talented players and have performed for their clubs.
"The key thing for us is to deny them time and force mistakes. You only gain experience at this level by going through these challenges. I just hope we deliver the performance we need."
McCaw is also hoping the All Blacks Haka can be performed without any further controversy. Wales accepted the challenge by standing their ground and staring out their opponents for more than a minute after the All Blacks had completed their routine and it took the referee to break up the stand-off.
"I do get a bit bored with all the fuss," said McCaw. "Everyone has their own opinion and we enjoy doing what is a pretty unique thing in sport.
"We are lucky to have the Haka and some teams face up to it while others do their own thing. I thought what Wales did was great, although there may not be anything new left to do.
"To be honest, it's what happens when the match kicks off that's really important. Maybe some teams make too much of what they should be doing in response.
"Plenty of All Blacks teams have tried to win all four Tests and to give ourselves this opportunity is really exciting. Our guys are playing five Tests in a row, which is a huge challenge, but we have this chance to win the slam."
England will name their team today, with New Zealand-born Riki Flutey desperate to overcome a hamstring injury to face his fellow Kiwis while Simon Shaw looks certain to replace the injured Tom Palmer at lock.
