The Miami Heat's loss to the Oklahoma City Thunder, in Game 1 of the 2012 NBA Finals, has already placed LeBron James and company in quite a hole.  

A Game 2 loss would make winning the series an even more difficult scenario for Miami, because only three teams in NBA history have come back to win the NBA Finals, after falling behind 0-2.

Ironically, the last team to accomplish this feat was the 2006 Heat, when they came back to beat the Dallas Mavericks in six games.
