Dallas Cowboys fans got a glimpse of everything they were hoping to see Friday night. Their new stadium dazzled. Tony Romo was darn good. And the Cowboys won, pretty easily. In the first football game at the nearly $1.2 billion Cowboys Stadium, Romo looked right at home, going 18 of 24 for 192 yards and sending Dallas on its way to a 30-10 victory over the Tennessee Titans in a preseason game. “It was incredible,” Romo said, comparing the atmosphere to a regular-season game.
