Mitchell has fueled Cleveland’s postseason surge with two straight 30-point outings, and the Cavs now hold a commanding series lead. But Miami has hope at home thanks to Herro’s hot shooting—he poured in 33 points in Game 2 and will need to repeat that performance if the Heat want to stay alive in the series.
