That lack of confidence - or more accurately dose of realism - would stem from the last match between these two sides, when the Warriors botched three field goal attempts before Broncos halfback Peter Wallace showed them how it is done.
"We haven't had to do it again since," Cleary said. "That was the only game this year where we've had to try to get one. You can practise all year but until you get in that situation ... hopefully it doesn't come that close."
It might not. There is a pronounced swagger about these Warriors. They expect to win tonight and win well.
"I think we are more ready this year, I feel like we are a better team in almost all areas," Cleary said. "Hopefully that will show [tonight]."
The round 22 loss to the Broncos and round 25 to the Dragons had provided valuable lessons.
"You can't drop your guard at any stage or get a bit sloppy at any point. Last week's game against the Cowboys was probably our best in some time in that regard."
The Broncos will be desperate not to let Darren Lockyer down in his last finals campaign. Cleary, though, suspects the emotional boost provided by the Lockyer circus might be running out.
" Hopefully they are all emotioned-out... I just reckon he's had enough fairytales. It might be time for us to have one."
