A rematch of the 2013 and 2014 National Basketball Association (NBA) Finals will take place today, Monday, when the Miami Heat host the San Antonio Spurs at the American Airlines Arena. 

The Heat already played two games in this year's preseason and have not won yet, losing 90–77 to the Charlotte Hornets and 100–97 to the Orlando Magic. 

In their most recent defeat, Miami was again led by All-Star forward Chris Bosh who scored 18 points, three rebounds, and three assists. 

Bosh, who suffered a life-threatening condition last season due to blood clots, again was the star for the Heat after dropping 14 points in their preseason opener loss to the Hornets. 

Helping Bosh in the recent defeat to the Magic was point guard Goran Dragić who had 12 points, two rebounds, and five assists and offseason addition Gerald Green who tallied 11 points, three rebounds, and one assist. 

Miami is still trying to find its footing since losing four-time Most Valuable Player (MVP) LeBron James before the start of last season. 

Meanwhile, the Spurs also started their preseason with a defeat as they fell to the Sacramento Kings 95–92. 

The Spurs' original big three of guards Tony Parker and Manu Ginobili and forward Tim Duncan did not play. 

But 2014 Finals MVP Kawhi Leonard did and was the leading scorer for San Antonio, recording 16 points, five rebounds, three steals, and one block. 

The Spurs' offseason additions forwards LaMarcus Aldridge and David West also made their debuts in the defeat but were not really that productive. 

Aldridge, who was one of the most coveted free agents early in the offseason, posted only eight points, three rebounds, and one steal; while West recorded five points, three rebounds, three assists, and one steal.
