Spoelstra resolute after loss: We're going to 'get it done' in Game 7

The Miami Heat are undeterred.

After Saturday's gut-wrenching loss on a game-winning buzzer-beater by Celtics guard Derrick White, the Heat are headed back to Boston for Game 7 with their season on the line.

Head coach Erik Spoelstra said Miami won't back down in the face of adversity.

"This is the way this season has been," Spoelstra said. "This is one hell of a series. At this time right now, I don't know how we're going to get this done, but we're going to go up there and get it done. And that's what the next 48 hours is about."

The Heat took a commanding 3-0 series lead before the Celtics rallied to claim the next two games by a combined 30 points, setting up the dramatic Game 6 in Miami.

Despite his team's letdown, Heat star Jimmy Butler echoed Spoelstra's sentiment. He added that Miami's facing the same situation as last postseason when it lost Game 7 to the Celtics in the Eastern Conference finals.

"I believe, as we all do, you're going to get the same test until you pass it," Butler said. "We were in the same position last year, and we can do it. I know that we will do it. We've got to go on the road and win in a very, very, very tough environment, but we're capable of it."

No NBA team has ever come back from trailing 3-0 to win a playoff series, and just three others have forced a Game 7.

However, those three squads entered the series as underdogs and played Game 7 on the road. The No. 2-seeded Celtics were heavy favorites coming in and host Monday's deciding contest.

The No. 8-seeded Heat won the series' first two games in Boston. They've also won four of six road playoff games against the Celtics since last year.
