The Wigan Warriors of 2016 have a 100 per cent record in the Super League and some steel inside them, according to coach Shaun Wane.
The spirit and toughness of Wigan's players was lauded by the coach after he watched them slog out a 26-25 win at Hull.
Wigan arrived by the Humber looking to make it four Super League wins out of four and at 20-6 up, that was on the cards.
But FC roared back with three tries in eight second-half minutes and led by four points heading into the last six minutes.
That left Wigan - without a host of first-team regulars - with work to do to prove their credentials, but they did it. Josh Charnley finished smartly by the flag to level things up and then Matty Smith landed two drop goals either side of Marc Sneyd's for Hull.
"We showed some character and I am very proud of all my players - it was an outstanding effort. We had virtually no ball in the second half and our completion rate was at 70 per cent," Wane said.
"We put ourselves under pressure, but the desire and guts and the heart we showed, with so many players out, was outstanding against a well-coached and athletic team."
Preserving a 100 per cent record looked a tough ask after Steve Michaels' second try for Hull, but Wane was pleased to see his men keep a cool head, adding that last year - a season that ended without silverware - they may not have done so.
"I was thinking 'stop giving them penalties and putting ourselves under pressure'," he added.
"We did that. There is still lots of improvement in us and you can't question our desire. We came here against a fantastic Hull team and got a win.
"The two drop goals were really good ones, but I'm happy because I believe Hull will beat many teams. Teams will come here and get pummelled.
"We are four from four and not played - we will improve for Leeds next week, another challenge and the players are buzzing.
"This time last year we were a bit petulant, giving penalties away, but this year we have that steel."
For Hull, it was a case of being on the wrong end of a result for the second week running.
They went toe-to-toe with Castleford last Thursday but slipped up late on as they went down 31-24 and the same happened again here.
"I thought we did enough to get the result but it was not to be. We dominated territory and field position," coach Lee Radford said.
"What was disappointing was having so much possession down their end and not getting as much as we could.
"The game was played down their end of the field. I can't knock their efforts but we've got to get better in a couple of areas.
"The amount of ball we had, we should have come away with more points and that's an area we want to improve on."
