Behind a penalty-free effort through two periods and another outstanding play-making performance by center Nathan MacKinnon, the Avalanche rolled past the Dallas Stars 3-0 on Wednesday night at the Pepsi Center. In a festive environment on the night before Thanksgiving Day, MacKinnon had three assists to extend his scoring spree to 20 points in 10 games and Colorado improved to 7-1-1 at home and 11-8-1 overall.
