The Suns relied on a storming second half to over-run St Kilda last Saturday night, kicking 10 goals to four after the main break to win by 13 points.
It was a theme they had carried with them through the NAB Cup as well, roaring home to almost pinch an unlikely win off North Melbourne, matching strides with the Sydney Swans and powering away from Melbourne in strong second halves.
So while their young bodies have taken a step forward under new high performance manager Stephen Schwerdt, Rischitelli says there's another factor at play.
"The boys are fitter physically, but mentally I think we're stronger," he said.
"In recent times you think other teams are going to come at us at half time or kick five or six goals on us, but talking to the boys, they didn't really feel like that (against St Kilda).
"More of a belief that we can finish them off, more than a mindset of 'I hope we're going to win'.
"That's the big step. In saying that, it's been one game, but it's something that's been pretty noticeable. Definitely it's been a big improvement."
Winning only fuels that belief, and after losing its first 14 games last season, notching a win straight away in season 2013 gives the Gold Coast plenty of confidence, Rischitelli says.
The Suns are preparing to play at the SCG for the first time in their short existence against the reigning premiers.
When the teams met just four weeks ago in the pre-season, the Swans stormed to a match-winning lead with a big second quarter.
Rischitelli said it was crucial to stay close early and match the Swans midfield of Josh Kennedy, Kieren Jack and co.
"They're strong boys, they're fit and they're great leaders," he said.
"They're a great midfield and it's no secret why they won the premiership.
"It's probably the best test we can get and we respect them, but there's no reason we can't match them."
