If Saturday’s game against Castres didn’t really matter, no one told the Saints players.
Because aside from a sluggish spell at the start of the second half, Jim Mallinder’s men poured everything they had into this Champions Cup clash.
Revenge wasn’t quite as sweet as it would have been had Saints still had a chance of progressing from Pool 4.
But you felt it was significant that, if only to display how far they have come, the team managed to avenge October’s 41-7 shocker at Stade Pierre Antoine.
Saints might not have been supremely slick during recent wins, but they have shown the character and composure every team needs.
While the game against Sale Sharks a few weeks back was largely comfortable, they were pushed all the way by Gloucester, Bristol and Castres.
But when it mattered, in the final 10 minutes of the match, Saints have prevailed.
They have shown steely desire and a calm heads to ensure they can now head to Montpellier in a much better mental place.
The drubbing in Dublin could have had severe consequences, but instead it appears to have galvanised Mallinder’s men.
They are still not playing the Champagne rugby some expect, but there was certainly more fizz about them in the games against Bristol and Castres.
The French team refused to fold at Franklin’s Gardens, roaring back from a 21-8 half-time deficit to level at 21-21 all.
But Saints showed their resolve, with skipper Tom Wood, who has embodied what this team has been all about in recent weeks, the fitting match-winner.
Wood has led his team-mates out of what he recently described as a ‘dark place’ and his consistency in a team that have lacked that quality has been nothing short of outstanding.
Teimana Harrison has stepped up in recent weeks, bringing added dynamism to a brilliant back row.
And with Louis Picamoles the player of the season so far, there is so much strength at Saints’ disposal.
There is no doubt the scrum could have been stronger against Castres, who got the upper hand in that area.
And Saints still missed several chances, especially when the French team were reduced to 14 men during the first period.
There were also defensive lapses and a lack of discipline when Castres started to turn up the heat after the break, but Saints battled to turn the tide.
It was a microcosm of how they have bounced back from four successive defeats and even if the necessary style isn’t always there, the steel certainly is.
And, crucially, the results are coming, with bonus-point wins accrued in the past two weeks.
Saints still boast a 100 per cent record in 2017 and that will come under threat in Montpellier on Friday night.
But if they can show the same pride and passion as they did against Castres, supporters will be as satisfied as they were at the final whistle on Saturday.
And in these weeks of seemingly inconsequential matches, that is all you can really ask for.
