Quebec's Olivier Rioux, world's tallest teen, chasing basketball dream at Canada Games

Olivier Rioux landed with a size-large exclamation point on Michael Meeks' radar when the Canada Basketball coach opened a photo in his inbox seven years ago.

Rioux was attending a kids basketball camp in Montreal, and posed for a photo alongside then-Detroit Pistons and Canadian team centre Joel Anthony, who stands a formidable six foot nine.

"Ron Yeung [Canada Basketball's manager of domestic development] sent me this photo of Olivier and Joel, and Olivier is about the same height, give or take an inch. Ron says, 'This kid is nine years old,"' said Meeks.

But Rioux is playing for Quebec at the Canada Summer Games this week in Ontario's Niagara Region with kids at least his own age, if nowhere near his size.

Meeks, who's at the Games to keep an eye on Canada's young players, said he's seen improvement in Rioux even over the past few weeks, but cautions that like any super tall player, he's a long-term work in progress.

"People see his size and their expectations are pretty high," said Meeks. "For me, it's the little things like his mobility and agility, how he's moving, how he conceptualizes the game — how much fun is he having competing and playing?

"This is important because we're in uncharted territories with Olivier, there's never been anybody that big at that age before. So, we're kind of cautiously optimistic that he's definitely moving in the right direction."

Rioux, who's from Anjou, a
