MIAMI -

The Miami Heat know what’s at stake Thursday night.

The players sounded like a broken record at their shoot-around earlier in the day, each saying that Game 4 is a must-win, as they don’t want to go back to San Antonio down 3-1.

But it was the Spurs breaking record in Game 3 that really got the Heat’s attention. The Spurs shot a finals record 76 percent from the field in the first half, and jumped out to a lead the Heat simply couldn’t overcome.

"As far as our effort was concerned, it was lacking," said Heat Forward Chris Bosh. "We owe it to ourselves and our organization, and we’re going to have to if we’re going to beat this team."

On Wednesday the Heat had a two-hour film session, going over mistake after mistake. While the experience was painful, they say it has prepared them for Thursday night’s game.

"It’s one thing when you have mistakes that you can’t correct," said Heat Forward Udonis Haslem. "It’s another when you have mistakes that are easily corrected."

"It would be an absolute waste of energy if we’re thinking ahead or in the past," said Heat Coach Erik Spoelstra. "All we’re thinking about is a great opportunity tonight at home and what we need to do to get the job done at home."
