A gruelling seven-game Eastern Conference series appears to have taken a toll on the Miami Heat in the opening game of the NBA basketball finals.
The defending champions lost 92-88 to the San Antonio Spurs in game one in Miami.
The Spurs beat Memphis in four games in the Western Conference final, giving them a week off while Miami struggled to overcome the Indiana Pacers four games to three in the Eastern Conference.
James says errors in the fourth and final quarter proved costly.
