Case for the defencepublished at 14:43 GMT
Wales v South Africa (15:10 GMT)
Image source, Huw Evans Picture AgencyWales - and particularly Tom Rogers - may have proved against the Al Blacks they can score points.
But the question remains whether they can stop opponents scoring many more.
In 2025, Wales have conceded 368 points in 10 fixtures at an average of 36.8.
By way of comparison with other Six Nations teams, England average 17.1, Ireland 18.9, Scotland 20.9, France 25.6, and Italy 31.9.
Cardiff has already witnessed three visiting teams - England (68), Argentina (52) and New Zealand (52) - score half a century of points this year.
Wales have held their opponents to fewer than 20 points just once since the 2023 World Cup - beaten 16-14 by England at Twickenham.
Tandy was defence coach with Scotland and the British & Irish Lions and assumed much of the responsibility, aided by part-time new coach Dan Lydiate.
And Tandy knows defence starts with discipline.
Wales have conceded 33 penalties in the November Tests so far, with fouls leading to a red card for Josh Adams and yellows for Ben Thomas, Tomos Williams, Taine Plumtree and Gareth Thomas.
"We have to be smarter because we spent 10 minutes in the 22 defending last weekend," said Tandy.
"The bravery, toughness, quality and physicality they put in was outstanding, but we wanted to do that less because you can see what we can do when we're at the other end of the field."
In contrast, South Africa have averaged 37 points and five tries per game from autumn successes against Japan, France, Italy and Ireland.
