SHAUN Edwards believes Wales reaped the rewards from sticking to their direct Plan A to get their Six Nations up and running against Scotland.

Wales have frequently been criticised for being too reliant on their power game, which failed to fire against England because of their set piece problems.

But Edwards says keeping to the script rigidly helped secure a 26-23 success at Murrayfield thanks to excellent tries by scrum-half Rhys Webb and centre Jonathan Davies.

"We had a lot more attacks against Scotland and went back to our Plan A, which we are very good at," said the defence coach.

"When we play to our Plan A we are a very, very good attacking team. When we fluctuate away from it we are not as good.

"We didn't get any set piece to play off against England and we got more phase-play rugby going against Scotland.

"If we are on our game we are a decent team and we had no field position against England, that's why offensively we didn't get anything off."

Not only did Wales threaten more with ball in hand but they showed steel in defence in the closing stages, ensuring that a late try was merely a consolation.

"The desperation from the lads was outstanding. We are a little bit upset we gave away at the end but that's just the perfectionist in us all and Alun Wyn Jones says he got under the ball," said Edwards.

"I was very impressed with our post-tackle work. I think we turned them over six or seven times on the floor and it's something that we excel at.

"I think we are the most proficient side in the world at turning teams over on the floor and I don't think we were rewarded for that against England, there was a clear holding-on penalty in the build-up to their second try."

Wales' success keeps alive their hopes of repeating their 2013 title triumph when they fought back from an opening day defeat to the Irish but they will need to up their game against a beefy French side a week on Saturday.

"Paris is a very difficult place to go," said Edwards. "Scotland are a slightly smaller team than France, who are enormous, but we don't mind tackling big players."
