The outstanding five-eighths of his era in the late 1960s-early 1970s said he can't remember a decline as acute as that which has seen Wales slump from Grand Slam champions to losing five games in a row.
Writing in Walesonline.co.uk, John said: "Losing is one thing but there is no recognisable team there anymore and things are disintegrating in front of our eyes.
"It is pointless at this moment pointing fingers at players or coaches because now is the time collectively coming together with the mighty All Blacks coming to town this week.
"The mind boggles with the likes of Dan Carter firing bullets from all over the place. It is quite frightening," he said.
Recent history suggested Wales cannot beat New Zealand and the game would need to be 'a massive damage limitation exercise'.
With Warren Gatland returning to coach the side there was an urgent need to lift the players, a process that wouldn't be helped by the injuries the side has suffered.
While there would be issues regarding the management of the team and especially the coaching of Gatland's assistant Rob Howley they needed to be put on the back burner for the moment. The reason?
"Because the All Blacks are coming. And one thing is certain, they will show us no mercy," John warned.
Meanwhile, on the same website, Delme Parfitt asked the question of who was more influential in their sport, Lionel Messi or Dan Carter?
"The comparison is a worthy one if for no other reason than both men are out on their own as the greatest modern day exponents of their craft," he said.
"Both have a swagger about them, and make it look as though they have more time than anyone else on the field when they have the ball. Both sit astride their teams as the central hub of attacking strategy."
And the reason for Carter's dominance and rating as the sport's superstar of the last decade?
"It's about spotting things, having an innate sense that something is definitely on and then the skill to make it happen. It's not about Plan A, it's more about Plan Z.
"That's what separates teams like Wales from the Dan Carters of this world.
"That's the reason on Saturday we will get the privilege of watching rugby's answer to Lionel Messi," Parfitt said.
