“I felt like I didn’t bring the intensity that the moment called for,” Murray said. “Even though I didn’t play terrible, I felt like I could have done a lot more. Most people that have watched the Nuggets play, when I have a game like that, I’m most likely going to bounce back.”

On Wednesday night, Murray responded with 34 points, 10 rebounds and 10 assists. He and Jokic became the first pair of N.B.A. teammates in any regular-season or playoff game to have triple-doubles with at least 30 points in the same game. Jokic finished with 32 points, 21 rebounds and 10 assists, becoming the first player in N.B.A. history to have at least 30 points, 20 rebounds and 10 assists in a finals game.

“It’s greatness,” Nuggets forward Aaron Gordon said. “That’s the dynamic duo right there.”

Murray scored 20 points in the first half, making 8 of 13 shots, including 3 of 5 3-pointers. Murray made a habit of making big shots to stymie Heat runs. Miami trailed by as many as 21 points.

“Jamal set the tone for their group, and he was aggressive, assertive,” Heat guard Kyle Lowry said, adding, “It made things a little bit easier for Jokic.”

Murray scored less in the second half, but made big plays defensively and off the ball.

“Forget the stats for a second — I felt Jamal’s presence, his energy, and he was here in the moment,” Malone said. “And for him and Nikola to do what they did tonight in a game that we needed to take, regain home-court advantage of the series, was special to watch.”

Murray delivered in a high-pressure situation. He felt burdened by the way he played in Game 2, but he didn’t shy away from the feeling.

“People ask: ‘It’s a big stage. Do you get nervous and stuff?’” Murray said. “You’re supposed to be. That’s what makes you care. That’s what makes you alive. That’s what makes you enjoy these moments.”
