DETROIT — The last time the Miami Heat attempted to storm back against the Detroit Pistons at Little Caesars Arena, it was nothing short of mayhem, falling a month ago in overtime in a game decided by Heat coach Erik Spoelstra calling a timeout his team did not have. This time, the Heat had their wits about them, with Tyler Herro again heating up late. But this time, the same result, an overtime loss, this time a 125-124 decision, in a game that ended with Herro off with a 3-point attempt just before the final buzzer. “It’s a shame,” Spoelstra said.
