Olivier started playing hockey as a 6-year-old, but even then he knew playing as a forward or defenseman was temporary since scoring goals never was a priority.
"I saw my father playing goalie all my childhood," Rodrigue, 17, said. "Every year he had his hockey school. I went there and I couldn't wait to start. The first time I put on the goalie gear was at his school.

"After that first day my mind was made up. And I haven't changed it since."
That's proven to be a wise decision. Rodrigue (6-foot-1, 159 pounds) is No. 1 on NHL Central Scouting's final ranking of North American goaltenders eligible for the 2018 NHL Draft, at American Airlines Center in Dallas on June 22-23.
Rodrigue went 31-16-3 with a 2.54 goals-against average and a .903 save percentage in 53 games.
He started and finished the season strong, playing for Hockey Canada. He had a 1.00 GAA and .942 save percentage to help Canada win the gold medal at the Ivan Hlinka Memorial Cup in August, and then had a 1.33 GAA and .949 save percentage in three games for Canada at the 2018 IIHF World Under-18 Championship.
"International experience can bring a lot of good things," said Dominique Ducharme, who coached Rodrigue the previous two seasons with Drummondville prior to being hired as an assistant coach by the Montreal Canadiens on April 27. "He entered the (Hlinka) tournament in the second game and never gave up the net. Playing in pressure situations, reacting well, behaving well and performing well brings forth that confidence."
Rodrigue grew his confidence after a rough start in the QMJHL. He was selected by Drummondville with the No. 3 pick of the 2016 QMJHL draft and played 41 of his team's 68 games in 2016-17. He had a 3.60 GAA and .878 save percentage.
"It was a great transition," Rodrigue said. "We had a good group of guys and we had fun playing together. We had good veterans. That year I wanted to force the coach to put me on the ice. It all depended on my play, but the goal was to start as many games as possible and to prove to everyone that I deserved my spot."
