Not only did Dwyane Wade continue his run of career highs, he sent the Detroit Pistons to a new low. Wade scored 31 points and set a personal best with 16 assists, leading the Miami Heat to a 103-91 win Tuesday night and handing the visiting Pistons their seventh consecutive loss -- Detroit's longest slide in more than seven years. Allen Iverson finished with 22 points and Tayshaun Prince had 18 for the Pistons (27-28), who fell under .500 this late in a season for the first time since 2000-01. "When D-Wade took over, that's when things went south," Prince said.
