The Miami Heat suffered a 123-121 loss to the Detroit Pistons at Little Caesars Arena on Tuesday night. The NBA Cup opener between Miami and Detroit was filled with dramatic moments, but Heat coach Eric Spoelstra’s one key mistake cost the team a chance at victory.

One of the most critical errors occurred in the final moments of the game, which caught the attention of former NBA player Jalen Rose. With the game tied at 121-121, the Heat had just given up a game-tying alley-oop to Jalen Duren from an inbound pass. Amid the chaos, Spoelstra tried to call a timeout, but there was one big problem as his team had no timeouts left.

This mistake was costly enough as the officials assessed a technical foul on the Heat for the timeout violation. The Pistons capitalized on their awarded free throw and possession, scoring two more points to clinch the victory.

This series of events sealed the win for Detroit, leaving the Heat with nothing but frustration. Fans in Miami were upset with Spoelstra’s blunder, as no one expected such a serious mistake from a seasoned coach.
