June 20

context: The Heat–Mavericks rivalry began in the 2006 NBA Finals, where the two teams met and both entering their first NBA Finals appearance. A year prior, the Heat had acquired Shaquille O'Neal. The Mavericks were led by Dirk Nowitzki, and the Heat were led by Dwyane Wade. Dallas had home-court advantage in the series due to a better regular season record (60–22) than Miami's (52–30) and took the first two games in the series, entering Game 3 with a commanding 2–0 lead. They looked set to win Game 3 until a rally by the Heat, including many free throws from Wade, resulted in the Mavericks losing the third game. The Heat won all of its home games, as the Mavericks dropped games 3, 4 and 5. In a highly controversial Game 5, a 101–100 victory for the Heat, Wade shot more free throws than the entire Mavericks team. Mavericks owner Mark Cuban as well as Nowitzki were both fined for acts of misconduct. During Game 6, the series returned to Dallas, where the Mavericks fell 92–95. Jason Terry airballed a three-point attempt that could have tied the game. Wade picked up the ball, throwing it in the air in celebration as the Heat won the NBA Championship, and its first one as well. Wade was named the Finals MVP.
