Connolly has played 123 first-grade games for the Eagles and his only grand final experience was with the Queanbeyan Kangaroos during a three-year stint in rugby league.
The 31-year-old said the premiership success at Queanbeyan only fuelled his desire to win one with his mates at Gungahlin, and in his final season of football he's daring to dream of a fairytale finish.
"I'm pretty confident, it's been a long time coming for me and I'm confident in what we can do and the team we've got and think we're a pretty good chance to knock them off.
"It's unreal, we've got old guys around the club from before I was born who are keen as, I've never seen the club the way it is at the moment."
"Everyone has just found their feet, we had a lot of fresh faces and young kids join the club this season," Connolly said.
"We're now playing our style of footy and and rolling into games [with confidence] as opposed to wondering if we're going to get knocked off every week.
"We were saying at training this week they should do an [ESPN documentary] 30 for 30 on us, we knew if we could just turn the corner we'd get a bit of momentum and we finally got it."
Tuggeranong have five ACT Brumbies playing this week and it will be a stunning upset if Gungahlin can send the minor premiers out in straight sets.
But Connolly warned anything can happen in finals and said if there was ever a time for an boilover - it was now.
"They've got a couple of Brumbies playing and we don't, but Mack [Hansen] is a future Wallaby and BJ [Edwards] is as good as any Brumby I've seen," Connolly said.
