The Golden Knights have 12 goals in the series from nine players, the most goal-scorers by any team through the first two games of a Stanley Cup Final. They have three goals from defensemen (Theodore, Zach Whitecloud and Martinez).
"I think our depth has been a strength all year," Vegas coach Bruce Cassidy said, "and it is the biggest reason why we're still here, why we beat Winnipeg, Edmonton, Dallas and why we're ahead against Florida. I just feel that we have the best team from player one through 20."
Anton Lundell and Matthew Tkachuk scored for Florida, but Sergei Bobrovsky was pulled in the second period after allowing four goals on 13 shots, including two on two shots in the second period. Alex Lyon replaced him and made 12 saves in his first game since April 21.
Bobrovsky has allowed eight goals on 46 shots in 86:56 in the series after giving up six goals on 174 shots in 321:05 across four games against the Carolina Hurricanes in the Eastern Conference Final.
Florida coach Paul Maurice was noncommittal on who would be his starting goalie in Game 3, though he also smiled when he was asked the question.
"We'll sweat about that for the next two days," he said.
The Panthers have lost back-to-back games for the first time since losing Games 3 and 4 at home against the Boston Bruins in the first round. They went 11-1 in their next 12 games, including 4-1 at home, to reach the Stanley Cup Final.
Teams that take a 2-0 lead in a best-of-7 Cup Final have gone on to win the series 90.6 percent of the time (48-5), including 92.7 percent when they win the first two games at home (38-3).
"They're halfway there and hopefully they're thinking about that a little bit as they're coming to Florida," Tkachuk said. "I think that could work in our favor, but we definitely have to prepare and give everything in this next one and just get a little bit of momentum back."
