Barrette actually learned that he'd be stepping into head coach Claude Julien's shoes just three short weeks ago.
He was driving with his grandfather when he received a phone call from his mother, Katia, who delivered the amazing news on behalf of Leucan, an association dedicated to supporting cancer-stricken children and their families.
"When she called, she said - 'Are you sitting down? I just want to make sure so you don't fall.' She told me that I was going to be watching a game at the Bell Centre from a loge, and then she said there was something else," recalled Barrette. "I jokingly said - 'Oh, I'm going in the room, too?' She answered - 'Yes, you are, and you're going to be doing the starting lineup!' My heart just started beating faster and faster."
Barrette had reason to be nervous, of course. He'd just been presented with an awesome responsibility, so the preparation had to begin immediately.
One of his top priorities was to look extra dapper for the big moment. Julien's players have some serious style, and he wanted to blend right in with the rest of the group.
And with a little help from a close family member, Barrette achieved that objective.
"My cousin's a stylist. He dressed me for the occasion. He actually dressed Tomas Plekanec in the past. That was the suit he made for me. It's all custom. It even has my name in it. When I told my family I'd be talking to the team, my cousin said that I had to wear that suit," mentioned Barrette, who received props from his favorite player, Brendan Gallagher, for his attire. "I remember walking in front of Gally when I entered the room and he said - 'Oh, looking sharp, buddy!"
