In front of a national television audience, the Celtics reminded the Cavaliers that the Eastern Conference still runs through Boston. They made five of their first eight 3-point attempts, took an 18-8 advantage midway through the opening quarter and never trailed again in a 120-117 victory Cleveland never quit.

Boston ended Cleveland's undefeated start to the season, but the Cavs were ready to learn lessons to prepare them for the big goal.
