Nikola Mirotic and Bobby Portis are starting to draw attention for their play together instead of their fight with each other. Mirotic scored 24 points, Portis added a career-high 23 and the Bulls blew out Boston 108-85 in Chicago on Monday night with Celtics guard Kyrie Irving sidelined because of a bruised left quadriceps. Co-owners of the NBA's worst record with Atlanta, the host Bulls (6-20) built an 18-point lead in the second quarter against the Eastern Conference leaders. And when Boston cut the margin to 12 in the fourth, the Bulls pulled away for their third straight win. Leading the way were two players who made headlines for all the wrong reasons before the season started.
