A healthy scratch for the first nine games of the playoffs, Reaves made his first appearance in Game 6 of the second round against the San Jose Sharks and played in all five games of the conference final.
"Everybody on this team has something to prove," Reaves said. "We call ourselves 'The Golden Misfits' for a reason. We're doing a good job of proving everybody wrong."
On Saturday, Golden Knights forward David Perron said it would be nice for either Reaves or forward Cody Eakin, who was also born in Winnipeg, to score in their hometown.
On Sunday, Reaves did exactly that.
"I saw the deflection, saw [Reaves] celebrating, and on the bench, I'm like, 'Man, I called that yesterday, I can't believe it,'" Perron said. "To see a guy like [Reaves] step up at this moment, it's awesome. We knew it was going to be somebody, and I called it out yesterday."
Although Reaves' goal was celebrated on the bench as it happened, the team mocked him in the dressing room during the second intermission.
"That's our group to a T," Golden Knights defenseman Nate Schmidt said. "A guy gets a goal and comes back in the locker room and it is not kudos but he starts getting ripped on for how hard he was celebrating. There were so many that I couldn't really keep track."
Regardless, the timing of the goal couldn't have been better.
"Couldn't be happier for [Reaves]. He's been saving it for 3 1/2 months, at least that's what he keeps saying," Golden Knights forward Erik Haula said. "I'm really happy for him, happy for the team. I guess proud is a good word."
