At the start of 2018, the Saints players talked about turning a page.
They spoke about wiping the slate clean.
They wanted to spark a fresh start.
And, most of all, they wanted to make Franklin's Gardens a fortress again.
Their stronghold had been struck by a string of sizeable defeats.
The likes of Saracens, Wasps and Ospreys travelled to Northampton and waltzed away not only with a win, but with a full five points.
Supporters could have been forgiven for thinking talk of turning things around was hollow.
They would have worried that their team did not have what it took to turn aims into reality.
But since 2017 became 2018, ambitions have indeed been realised.
The Saracens shocker at Allianz Park aside, Saints have shown a new-found steel.
And they have managed to live up to their promise to bring the pride back.
Not only did they show immense character to claim a gritty win at Sale last weekend, but they have now won three successive home matches.
They are still 100 per cent at Franklin's Gardens in the new year.
After securing a last-gasp success against Gloucester and producing a classy performance against Clermont Auvergne, they hammered Harlequins.
Saints did what they have had done to them so often this season: they racked up a bonus point before half-time.
In fact, it came in the first 30 minutes as they totally overwhelmed their opposition.
At one stage, Saints had made more than 300 metres, while Quins had struggled to make 30.
Even given the disparity in strength of the two sides, that was quite something.
Saints sent out their big guns - and they fired.
But this wasn't just about players like George North and Piers Francis.
This performance was built on the dynamism of players such as Mike Haywood and Tom Stephenson, both of whom are products of the Saints Academy.
It was also built on the sheer graft of the likes of Jamie Gibson and David Ribbans, who got around the field at a rapid rate of knots.
All in all, a Saints side with semi-final in sight delivered when it mattered.
Now they need to do it all again in the Premiership in the coming weeks.
They have momentum and they must use it to carry them past Bath at The Rec on Friday night.
But make no mistake, the west country side will be facing a very different Saints outfit to the one that finished 2017 with a 50-21 defeat to Harlequins at Twickenham.
This is a Saints side that now believes again.
And the supporters do, too.
The feel-good factor is back at the Gardens, and how Saints would love to maintain that in the weeks and months to come.
If they can, not only could a much more promising league position come their way, but a piece of silverware may also be making its way into the trophy cabinet in March.
