That last game was particularly interesting because it involved one of the greatest coaches of this generation making an incredibly uncharacteristic mistake at the worst possible time. With the game tied at the end of the extra period, Erik Spoelstra called a timeout … even though the Heat didn’t have any.

Miami Heat head coach Erik Spoelstra admitted that his own “horrendous mistake” cost the team in its 123-121 defeat to the Detroit Pistons in the NBA Cup on Tuesday.

Spoelstra was assessed a technical foul, and Pistons guard Malik Beasley sank the ensuing free throw, giving Detroit a late lead the club would not relinquish. After the game, Spoelstra took accountability for the mistake that led to Detroit's victory.
