Like each of the previous stops in his NHL career, Perron has impressed with his skill, and his perseverance.
"I knew him from coaching against him with other teams," Vegas coach Gerard Gallant said. "He was a competitive guy, good hands, good skill and [can] make plays.
"Actually, I know his personality now and I have a lot more respect than I did for him before. He is one of the first guys here every day. He is a true pro, and like I said, he likes to play hockey."
Vegas general manager George McPhee said Perron has been a pleasant surprise.
"David's had a terrific year, a career year," McPhee said. "He turned out to be a far better playmaker than we originally thought. He really hangs on to the puck and holds people off and uses his strength."
Perron had 66 points (16 goals, 50 assists) in 70 games. He has seven assists in 11 Stanley Cup Playoff games.
Still, Perron wants more.
This is his first time in the Stanley Cup Final. It is his first time past the second round, in fact. He wants to finish his dream, the one that started so long ago in Melancon Arena, St. Jerome's home, and figuratively a million miles from the Las Vegas Strip.
"I'm just happy to be here now," Perron said. "What this team has accomplished from Day One to now, it feels like it has been way longer than a year. You remember the first few weeks of the season, and it almost feels like a couple of years ago because there has been so much that has been accomplished, but at the same time, there is so much more that we can do."
Perron knows that better than most.
