Wales defence coach Shaun Edwards insists that he was "happy" with their 'blitz' defence in their defeat to Ireland at the weekend.
Wales defence coach Shaun Edwards has responded to criticism that the team's 'blitz' defence was not effective in their defeat to Ireland at the weekend.
Former Wales international Gareth Llewellyn questioned the tactic following defeat in their Six Nations opener, but Edwards has insisted that he was "happy".
"I was happy with the blitz defence, but I wasn't happy when we didn't blitz," Edwards told BBC Sport.
"You notice from the scrum try we didn't blitz, you know people are saying the blitz defence is not working. The blitz defence works. We just need to do it at the right time."
The tactic involves defenders moving quickly towards their opponents, with the aim of closing the space.
