But what Saints showed on Saturday afternoon was that not only are they capable of delivering improvement through a week, but also during a game, too.
And they did it in some style at Kingston Park.
Because after a tough opening 20 minutes in which the ill discipline that has blighted some parts of this season continued, Saints well and truly sorted things out.
They shed their sinners tag and delivered a defensive display that laid the foundation for one of their finest wins during Chris Boyd's time in charge of the club.
Saints not only limited the Falcons, who struggled to come up with solutions to the away side's linespeed during most of the afternoon, to just eight points, they scored 44 of their own.
And what a tonic this was after the black, green and gold had scored just 12 points in their past 168 minutes of rugby.
Tom Collins' 23rd-minute try, created by a monstrous tackle from Fraser Dingwall, seemed to breathe new life into this Saints team.
They suddenly showed some real belief, in attack and defence, stopping the Falcons in their tracks at every turn.
It was a hugely impressive away performance in the first game on the road in 2022.
And supporters will hope it can be the springboard to success in the calendar year.
Of course, you can't get too carried away after just one win.
But this was some win.
And the players and fans who made the long trip north earned the right to savour this success.
It was what everyone of a Saints persuasion will want to see more of in the weeks and months to come.
Europe beckons once more in the next two weeks, but the Premiership is the prize Saints want now.
And they must produce plenty more performances of this nature before the campaign is out if they are to achieve their aims.
If they can show the kind of confidence they exhibited on both sides of the ball at Kingston Park, it will be more than a start on the journey.
There are of course much tougher tests lying in wait.
But the way Saints dealt with a Falcons team who had beaten them in seven of the previous eight meetings between the sides in the Premiership can be seen as nothing but a positive.
After a tricky start to 2022 against Saracens, Saints have lift off.
And they will know this kind of showing now needs to become their new normal.
