Wigan head coach Shaun Wane described his side as "ordinary" despite their 40-22 win at Wakefield.
Winger Joe Burgess scored a hat-trick as the Warriors secured a first away win in Super League since their victory at Catalans in July last year.
"It was ordinary for our standards," Wane told BBC Radio Manchester.
"We got two points, we found a way to win but some of our defensive reads and the way we reacted to certain things was really poor for me."

Securing two points at Wakefield moved last year's losing Grand Finalists into second place ahead of the other fixtures at the weekend.
Despite watching his side run in eight tries, Wane could not hide his frustration at what he saw at Belle Vue.
"With the ball, I never panicked - I knew we could score, but the defensive side of it really disappoints me," he added.
"We are a young team and I think there was a little bit of mental softness.
"I might be being a bit harsh on the players, because we scored so many points, but I think players know themselves we were below our standards."
