Miami Heat vs San Antonio Spurs Live Stream Free: Watch Online NBA Finals 2013 Game 6 at 9:00 PM ET

Nobody expected the Miami Heat to be in this situation. The Heat of LeBron James, Dwyane Wade, and Chris Bosh were going to sweep through the NBA playoffs and Finals against all competition. The San Antonio Spurs would not steal another championship from the Heat.

Well, guess what, the Heat are one loss away from disappointing the basketball world.

This season they were the NBA's best team, one that lost three games in three months and made losing three times in one series look unlikely, if not downright unimaginable.

The Spurs can finish Miami off Tuesday night in Game 6 of the NBA Finals, reaffirming themselves as one of the league's greatest franchises.

If so, the Heat's Big Three once again go from celebrated to devastated.

"We're going to see if we're a better team than we were our first year together," James said.

The Spurs took a 3-2 lead with their 114-104 victory Sunday night. Tim Duncan, Tony Parkerand Manu Ginobili were all brilliant again, and Danny Green added to what could become one of the most out-of-nowhere finals MVP campaigns ever.

One more victory makes the Spurs 5-0 in the NBA Finals, keeping pace with Michael Jordan's 6-0 Chicago Bulls as the only teams to make it here multiple times and never lose.

"We understand Game 6 is huge," Tony Parker told nba.com. "Obviously, you want to finish in the first opportunity you get. We understand that Miami is going to come out with a lot more energy, and they're going to play better at home. They're going to shoot the ball better. Their crowd is going to be behind them."

The Heat would also host Game 7 on Thursday. They're trying to join the 1988 and 2010 Los Angeles Lakers and 1994 Houston Rockets as the only teams to rally from 3-2 down by winning the final two on their home floor since the NBA Finals went to a 2-3-2 format in 1985, according to espn.com.

"We're in a position where it's a must-win and everything that we've done all year comes to this point, and we have to win," Heat guard Ray Allen said to espn.com. "We've found ourselves in so many situations this year, and we've thrived in tough moments because this is a tough team. We will be ready for Game 6."

So will the Spurs, and the Heat know it.

The Game can be viewed on the American Broadcasting Network.
