LATE in the season, Brisbane's set shot goalkicking cost it dearly, but in September, it's been its saviour.

When the Lions have needed it most, their radar has been deadly accurate in the second halves of comeback wins over Greater Western Sydney and Geelong in the past fortnight.

Against the Giants that was best exemplified by the pair of set shots Joe Daniher nailed in the dying minutes to complete a dramatic victory.

And against the Cats, Charlie Cameron and Cal Ah Chee made the most of their chances following marks inside 50.

It's been a huge turnaround from the final month of the home and away season where costly misses in big moments against the Giants and Collingwood cost them victories and a place in the top four.

Cam Rayner, who iced last weekend's win with a 50m dart off his left foot, said Brisbane had rediscovered its "enjoyment" and was putting misses behind it.

"No one misses goals deliberately and everyone knows that in the team," he said on the eve of the Grand Final.

"If people miss goals, you never see guys bite back at each other or snap, it's everyone telling each other to smile and get ready for the next one.

"The amount of times it's happened that that same person gets an opportunity and finishes the next one has been really pleasing."

During the home and away season, Brisbane converted at just 50 per cent on its set shots, ranked 16th in the competition.

However, with the games on the line in the past two weeks, they've nailed 63 per cent of their set shots after half-time to play pivotal roles in five and 10-point victories, respectively.

"People are going to miss goals," Rayner said.

"Mistakes happen and obviously in Grand Finals mistakes are heightened, so the importance of staying connected and coming back to your teammates is one thing we've been working on."
