But the teenager has already made a name for himself after earning AFL Dream Team squad selection for May 10's Hall of Fame tribute match.
The 19-year-old West Australian is not only the youngest player picked in either the Dream Team or Victorian squads announced today - he is also the most inexperienced.
He has racked up just 13 senior matches since being drafted by the Lions with pick No.4.
Dream Team coach Mark Williams of Port Adelaide said his 40-strong squad had been picked on form - not reputations.
And Williams knows first-hand how good Leuenberger is.
The youngster helped the Lions complete a remarkable 67 point turnaround to beat Port last round.
"I thought Leuenberger played fantastic last week and that's a fact," Williams told reporters in Adelaide today.
"That kid might not get in at the end but to be picked in this famous game as a young kid says he's doing something right.
"We are picking the players that are in good form, not players based on their reputations and I think that's only fair."
Leuenberger was one of a total of seven Lions players named in Dream Team and Victorian squads today.
Jonathan Brown will captain Victoria while fellow Lions co-captains Nigel Lappin and Luke Power are also in line to wear the big V along with Brisbane forward Daniel Bradshaw.
Lions co-captain Simon Black has been named in the Dream Team along with Leuenberger's ruck partner Jamie Charman.
Leuenberger is already doing his best to make the final Dream Team cut.
His AFL education was fast-tracked against Port last round when he was forced to play a lone hand following the last minute withdrawal of Lions No.1 ruckman Charman (calf).
The second year ruckman was thrown into the deep end against Port, going head to head with All-Australian Brendon Lade and the equally daunting Dean Brogan.
"If he was a 28-year-old mature ruckman you would have said he got his pants pulled down," Lions coach Leigh Matthews said of Leuenberger's game against Port.
"But he's a 19-year-old kid who is developing and we thought he was really competitive.
"He got pretty much beaten in the ruck as you would think against two mature ruckmen like Lade and Brogan.
"But he did enough around the ground to still be a really valuable player despite ... not being big and strong enough at the moment."
Charman is again in doubt for Saturday night's Gabba clash with ladder leaders Hawthorn.
But Leuenberger clearly loves a challenge - he played his best game last year when Charman was injured against Sydney and the teenager stood tall against Peter Everitt and Darren Jolly.
