It was a storybook finish for each of them. Subban, who had a mere 62 minutes of previous NHL experience, made 21 saves in defeating the Bruins 3-1 at T-Mobile Arena. Tuch scored his first NHL goal, at 14:38 of the second period, and assisted on Vadim Shipachyov's first NHL goal 3:08 later.

"It felt good," Subban said. "Really good. Honestly, you have no idea, after the last couple years and stuff."
Subban, 23, was selected in the first round (No. 24) of the 2012 NHL Draft by the Bruins, and his career had been seemingly stalled with Providence in the American Hockey League.
The Golden Knights, with an eye fixed on the future, claimed Subban on Oct. 3 after the Bruins placed him on waivers. Their plan was to ease Subban into the fray, letting him work with goaltending coach David Prior.
But the future became the present when Fleury sustained a concussion after taking a knee to the head against the Detroit Red Wings on Friday. The Golden Knights placed Fleury on injured reserve Sunday, along with forwards Erik Haula and Jonathan Marchessault.
This paved the way to recall Tuch and goaltender Maxime Lagace from Chicago of the American Hockey League, and Shipachov, who had been working out on his own in Las Vegas with permission from the Golden Knights.
Subban, the younger brother of Nashville Predators defenseman P.K. Subban, had played two games with the Bruins. His NHL debut was on Feb. 20, 2015, against the St. Louis Blues and didn't go smoothly; he allowed three goals on three shots during the second period.
On Sunday, he was 30 seconds from a shutout against his former team. Bruins forward David Pastrnak was credited with the goal, but the puck went off Golden Knights forward William Karlsson.
"I thought (Brad Marchand) was going to tuck it short side," Subban said. "Then he went around the net. I'm like, 'Oh boy, I'm in a tough spot now.'"
There were long spells of inactivity, however. Subban chuckled when he was asked if it was hard to stay focused when he wasn't facing a lot of shots.
"Not in a game like this," he said. "Maybe for a guy like (Bruins goaltender) Tuukka (Rask), a veteran guy. For me, you've got to find a way. You want to make it work. You want to get your first win."
