MIAMI – The Miami Heat already were at an emotional loss watching Dru Smith being escorted off the court in the second period with a leg injury. For a while, they also seemed at a loss against a team trying to lose. Eventually, if not emotionally, order was restored enough for Erik Spoelstra’s team to snap a three-game losing streak with Monday night’s 110-95 victory over the Brooklyn Nets at Kaseya Center. “We’ll just have to see tomorrow,” Spoelstra said of Smith’s injury, which stands as potentially season-ending.
