After an “awesome” offensive performance, Phoenix Suns coach Mike D’Antoni wondered whether his team could one day score on every possession. He admits it’s a pipe dream. Opponents might call it a nightmare. Leandro Barbosa scored 35 points, Canadian star Steve Nash had a season-high 18 assists and the Phoenix Suns set a season high in points, beating the Toronto Raptors 136-123 on Wednesday night.
