Wayne Pivac shrugged off the suggestion Wales had luck on their side as they overcame England 40-24 to wrap up a Six Nations Triple Crown.
Wales have now beaten Ireland, Scotland and England across their opening three matches to take a five-point lead at the top of the standings, though second-placed France have a game in hand.
Saturday's victory was not without its contentious moments, however, as the calls of referee Pascal Gauzere took centre stage in the first half.
First, the French official allowed Josh Adams' opening try to stand, despite having given England little time to set themselves from a Wales penalty, with the referee having asked Owen Farrell to speak to his team.
Gauzere then made the on-field decision to award Liam Williams' try, with TMO unable to definitively prove that Louis Rees-Zammit had knocked on in the build-up.
Wales benefitted from a red card in their wins over Ireland and Scotland, but Pivac put the victory against England in Cardiff down to his team's application.
"Some people are going to say that, they'll say it's been on our side for the last three matches, but you've got to be in games to win them," Pivac told BBC Sport.
"England put a lot of pressure on us and came back, each time we hit them they came back again, so it was a hell of a game and a lot of resilience shown from our boys."
Asked if he had any sympathy for England, Pivac added: "I think when you give away that many penalties – one player giving away five penalties – I think you’re lucky not to concede a yellow card to be honest. I suppose you could argue either way."
Wales lost four of their five games in last season's Six Nations campaign, finishing fifth above winless Italy, yet now look on course for a Grand Slam.
"Time. A bit of time," was Pivac's explanation when asked how his team have turned their fortunes around.
"We've picked a squad to get results in this tournament and we had a good look at some players in the last tournament that we've well and truly documented, but certainly time together and I think you can see there's a good bond growing in this group.
"They enjoy winning things, as they did under Warren [Gatland]. Hopefully we can press on."
