It might be getting ahead of things, but that's exactly what the Warriors have been guilty of several times this season.
Like taking on a severely depleted Penrith side in round 17, or facing a Titans teams they had topped in 14 of their previous 15 encounters.
And like playing a bottom of the table Bulldogs outfit, with a finals spot on the line.
There was an edge of complacency in those games, and it told.
It's hard to reconcile, given the courage and conviction the team has exhibited on other occasions in 2018.
The good news is the Warriors have perfected the art of the bounce back this year.
It shouldn't take the anger and disappointment of a flat loss to provide motivation, but that's often been the case.
That might happen again this week, given the bizarre circumstances of last Sunday afternoon.
The Warriors haven't qualified for the playoffs for seven years, encompassing more than 180 rounds of football and a whole generation of players.
But unfortunately, it didn't seem to matter on Sunday.
For whatever reason, the Warriors couldn't seize the moment.
There was no sense of urgency, given what was at stake.
Sure, it happens to sports teams.
Unfortunately it has happened to the Warriors too often.
The team has made some extraordinary gains this year, and can look back on some wonderful performances.
But that won't mean much if the Warriors don't finish the season well; it's like leading in the Melbourne Cup as the field passes Flemington's clock tower, before fading to the middle of the pack.
It's sport, and anything can happen. And only insiders will know if some players are carrying knocks into games, or affected by illness.
But something was badly amiss at ANZ Stadium.
On an occasion screaming out for some senior Warriors to step up, instead the biggest moments were orchestrated by a 22-year-old Bulldog playing his seventh NRL game.
It's part of the mystery of the Warriors.
In their defence, they are playing in the toughest, most competitive domestic sports league in the world (maybe alongside the English Football League Championship), but they have a habit of doing things the hard way.
The victory at Wollongong three weeks ago was an extraordinary effort, one of the grittiest performances in the club's history.
That win set them on course for a possible home playoff, but it's a much tougher path now.
Hang on for the ride.
