IF Saturday's clash with their rivals was the acid test for Wolves, they passed it with flying colours.
Jon Clarke and Martin Gleeson spoke last week about how victory would be a big step forward for either side after impressive starts to the campaign.
Wolves won three of their first four games last year but this time clinched a fourth win out of five for the first time since 1999.
It was also the club's fourth consecutive win against Wigan - the first time that has happened since a winning streak between 1980 and 1982.
And on Saturday's evidence, Wolves are simply better than Wigan.
What's more, Paul Cullen's men are starting to look like a side with the steel and consistency to mount a real challenge at the top of the table.
No side in Super League would relish coming to The Halliwell Jones Stadium at the moment.
Cullen called for Wolves' best performance of the season and he got it.
Wigan have never won at The Halliwell Jones and never looked likely to break that duck in front of a sell-out crowd.
Wolves used the skills that have given them the best attacking record in Super League - scoring 153 points in their first five games - to take an early lead.
They then defended their line resolutely during the crucial moments, particularly when Louis Anderson had been sent to the sin bin midway through the first half.
Referee Steve Ganson was rarely out of the action, giving 27 penalties during the game including 12 in the first 17 minutes to break a record for the season so far.
But Ganson was spot on when he dismissed ex-Wolves loanee Richie Mathers for a swinging arm to the neck of 6ft 3in Matt King 10 minutes into the second half.
Mathers had both feet off the ground and it was arguably the worst tackle in a Wolves match for a few years, although the full back did make a point of apologising to King and Cullen after the match and stressing that the challenge had not been intentional.
After a six-minute delay as King was stretchered off, Wigan were down to 11 men following Michael McIlorum's sin-binning.
That allowed Wolves to finish off the game, with Vinnie Anderson and Paul Johnson - both possibly more comfortable in the pack but playing at centre and wing - using their pace for a fine long-range try.
All this with Kevin Penny sat in the stand. Wolves really do have some squad this year.
