The Philadelphia 76ers faced a test Monday night against the Cleveland Cavaliers. The upstart Sixers had another game in which to measure progress. How do they stack up against LeBron James and the Cavaliers, who have represented the East in the NBA Finals the past three seasons? It was also a test for the Cavs, who faced a quality opponent on the road following seven connective victories. The Cavs aced the exam, and Sixers did not. Cleveland won for the eighth consecutive time, beating the Sixers 113-91. Cleveland is 13-7 and a half-game behind Detroit for second place in the East, while Philadelphia fell to 11-8. The Cavs’ offense continued to hum — James had 30 points, and Jeff Green, Dwyane Wade, Channing Frye and Kyle Korver combined for 50 points off the bench — and their defense showed more improvement, holding the Sixers to 37.6% shooting, including 10.7% on three-pointers.
