But Jones also believes Wales have a firm foundation on which to build their bid for a third RBS 6 Nations title this season.
Wales will win the Triple Crown if they beat England at Twickenham on Saturday, leaving them then requiring home victories over Italy and France to guarantee Six Nations silverware and a Grand Slam following tournament clean sweeps in 2005 and 2008.
And such an achievement would inevitably draw comparisons between the current Wales squad - World Cup semi-finalists last autumn - and its successful predecessors.
"We've had two Six Nations (titles) before, and I think both were out of the blue," said Jones, who captained Wales to Grand Slam glory four years ago.
"This campaign feels the most settled and constructive one we've had, built on a foundation and a confidence where we are going into a game with a plan and implementing it.
"International rugby is about week to week. Time will tell where this squad stands, but as players it is not something you take notice of.
"Trophies and silverware take care of themselves, the only thing we can focus on is the game. You might not be involved next week or in the title-winning game - your focus is the here and now."
Jones, who matched Ieuan Evans' feat of captaining Wales 28 times when Scotland were defeated in Cardiff nine days ago, will be 31 four days before a possible title decider and Grand Slam clash against France next month.
He also has the rare recent distinction among Wales skippers of leading his team to victory at English rugby headquarters. On that occasion four years ago, it kick-started a Six Nations title and Grand Slam season.
But, unsurprisingly for a player of such experience and stature, Jones gives short shrift to those who have suggested that Wales only need turn up in four days' time and England will be sunk.
"For us to go up there and win, we are going to need a good set-piece, we will need to be disciplined and we are going to have to be clinical," he added.
"As soon as that first kick goes up in the air there is nothing in your mind that says 'we are favourites to win this, or we are the underdog'.
"You focus solely on your job, what is required of you and what it takes to win.
"Twickenham is a tough place to go. They will be looking to impose themselves on us with their set-piece game, I would imagine, and we have got to be ready for that.
"When we there four years ago, we got caught early on, but because we minimised the damage done in that period we were still in contention at half-time."
