Former Wales captain Gareth Llewellyn says there would be no sense in replacing coach Warren Gatland before the 2015 World Cup.
Defence coach Shaun Edwards hit back at suggestions that the New Zealander is under pressure.
"It wouldn't make any sense at all to change the coaching staff," said Llewellyn.
"Our track record of sacking coaches in the year of the World Cup and the results we get thereafter is appalling. Let's not make the same mistake again.
"He'll put himself under pressure, he'll be frustrated. But under pressure for his job? I don't see it."
Wales have won just once in 27 games against New Zealand, Australia and South Africa since Gatland was appointed in 2007.
Wales failed to make it out of the World Cup pool stages in both 1991 and 1995 after parting company with their coaching staff shortly before the tournaments began.
Two months after coach Alan Davies stood down, Llewellyn was part of the Wales team which bowed out of the 1995 World Cup after losing to Ireland.
Wales also failed to make it out of their pool at the 2007 World Cup, leading to Gareth Jenkins's departure, only a year after being appointed coach.
"While the results are frustrating for the team, the public and for the coaching staff, we are a year away from the World Cup," said the former Bristol and Harlequins lock.
"To be fair to the players and to any coach, they want more than a year's build-up.
"As frustrated as we all are with the run of results against southern hemisphere teams, outside of that we've done pretty well."

South Africa laboured to a 22-6 win over Italy last weekend and Llewellyn is confident Wales can record a first win over the Springboks since 1999 on Saturday.
"They've been fairly indifferent in form. They're very physical and very direct which kind of suits the way we defend," he said.
"They're a better fit for us than the other teams in terms of trying to knock one of them over.
"I think we have got a genuine opportunity on Saturday."
