They start 2018 on a nine-game losing streak - two shy of the club's all-time worst run of defeats - and desperate to erase a six-season finals absence.
"I'm not too fussed what people say outside," Kearney said.
"But internally we know that if we play close to our potential every week, consistently, then we give ourselves a great opportunity to play at the back end of the year.
"That's certainly not beyond us."
The Warriors have undergone a massive overhaul with Blake Green, Adam Blair, Tohu Harris and Gerard Beale headlining their recruitment drive.
They head into Saturday's season-opener in Perth full of confidence like their opposition South Sydney, who are facing their first test under new coach Anthony Seibold.
The sight of Greg Inglis striding onto Perth's Optus Stadium, after a year on the sidelines due to a torn ACL, will fill his teammates with confidence.
They appear to have more strike power this year with 2017 Queensland player of the year Dane Gagai joining Inglis in the centres.
Under Michael Maguire, they were criticised for being too robotic and halfback Adam Reynolds said the shackles had been loosened under Seibold.
"We do have the licence but we have to respect the ball and make the most of opportunities when we do get them," Reynolds said.
"Respect for the ball is the No.1 priority."
STATS THAT MATTER
