The defending champions Miami Heat are set to take court in a must-win game at the AT&T Center on Sunday night against the San Antonio Spurs.

No team has rallied back to win the championship after going 3-1 down in the series and it will be a colossal task for the Heat to defend their title. Four-time MVP LeBron James is hoping to turn the tide, knowing the odds are heavily against the Heat.

"It would be in the range of, Why not us?" James said. "Why not us? History is broken all the time. And obviously we know we're against the greatest of odds.

"History is made to be broken, and why not me be a part of it? That would be great. That would be a great story line, right? But we'll see what happens. I've got to live in the moment, though, before we even get to that point."

James said Miami are taking it one game at a time and not thinking about forcing Game 7. The Heat failed to match the tempo set by San Antonio in last two games and James stressed on a need of reducing errors to cut the series deficit.

"We need to win one game," he said on Saturday. "That's all we can think about. We can't think about forcing a Game 7. We know we're against the greatest of odds. If we limit our mistakes, we give ourselves a good chance to win it. If we don't, then it will be over tomorrow night, and it's just that simple."

San Antonio won the last two games in dominating fashion by racing away with the lead in the first quarter. They never trailed by more than two points in either of the encounters and remained in control throughout the contest.

The Spurs' Danny Green said the team is looking to carry the momentum in the upcoming game and aiming to secure the home-court advantage without thinking about winning the series in San Antonio.

"We've got to act like we're coming into it like it's a road game," Green said. "It's a mentality thing. We have to come up with the same mentality we do on the road and try to protect home court and play with desperation."

Miami's coach Erik Spoelstra said the series is not over yet and they will have to fight and snatch a win in Game 5 against the Spurs.

"We're not so entitled or jaded that we above have to fight for it, and that's what it is right now," Erik Spoelstra said. "It's competition. So we've got to find a way to fight and get this next game, and that's what it's all about."
