On defense, Boston yielded only 1.05 points per possession, with Miami shooting 8 for 32 (25%) from 3-point range and producing only 18 assists compared to 15 turnovers. For the full playoffs, the Celtics are scoring 1.17 points per possession, and Boston leads the postseason with 60.0% true shooting. The Celtics have a 2.01 assist-to-turnover ratio, and Boston's 3-point shooting is devastating.
