The Heat lost the opening game, but then reeled off four wins in a row to secure the title in front of their elated fans.
The first four games were closely contested, and no team won by a double-digit margin, but the Heat dominated Game 5 and won 121-106.
LeBron James capped off an incredible postseason with 26 points, 13 assists and 11 rebounds.
The 2012 NBA MVP signed with the Heat in 2010, and the Ohio native took a significant amount of criticism for leaving the Cleveland Cavaliers to sign with fellow superstar Dwyane Wade.
James, in his ninth season, is considered the best all-around player in the NBA, but has been lambasted for his inability to come through late in games and push his team to a title.
Team president Pat Riley is responsible for drawing James and Chris Bosh to Miami to create the core of the championship roster.
The Heat were upset in the finals last season when they lost in six games to the Dallas Mavericks. After the loss, critics felt that head coach Erik Spoelstra should step down and allow Riley to take control of the team.
Even with the Big Three in place, questions remained about the rest of the roster.
Mike Miller provided an unexpected spark off the bench. He hit seven three-pointers and finished with 23 points.
Shane Battier, who signed with the team this season, finished with double-digit points in three of the five games in this series.
All the questions about Spoelstra’s coaching, the role players and James’ ability to win a championship have been definitively answered.
This is the first championship for Spoelstra, James, Bosh, Battier and Miller, while it is the second for Dwyane Wade.
