Why the Celtics can cover

Boston is above-average on the offensive end, scoring more than 1.11 points per possession. Portland also struggles mightily on defense, with the Blazers ranking second-to-last in the NBA in defensive efficiency (1.16 points allowed per possession) and 2-point shooting allowed (54.9 percent). Boston is dynamic on the offensive glass, grabbing 29.3 percent of its own missed shots, and the Celtics land above the NBA average in effective field goal percentage (54.3 percent) and true shooting percentage (57.5 percent). 

The Celtics are also strong defensively, and Boston is allowing only 1.06 points per possession in the last 10 games. Boston is a top-eight team in fast-break points allowed (11.5 per game), points allowed in the paint (44.8 per game) and assists allowed (23.5 per game), with above-average marks in both steals (7.9 per game) and blocks (5.3 per game). Portland is strong on offense, but it is the NBA’s worst team in generating assists (20.3 per game), making the job of the defense a bit easier.

Why the Blazers can cover 

Portland is led by a stellar offense, and the Blazers have an elite backcourt in Damian Lillard and CJ McCollum. Lillard leads the team in averaging 28.7 points and 7.6 assists per game, with McCollum adding 23.5 points per game. As a team, the Blazers are scoring 115.9 points per 100 possessions for the season, and they are elite in several categories. Portland takes care of the ball at a fantastic level, committing a turnover on only 11.6 percent of possessions. The Blazers are also stellar in both making a lot of 3-pointers (16.0 per game) and maintaining tremendous accuracy, making 38.0 percent of their long-range attempts. 

Portland is above-average on the offensive glass, and it can generate second-chance opportunities against Boston. While the Blazers are not terribly stout defensively, they can win the free throw battle against a Boston team that struggles to both generate free throws and prevent their opponents from taking them. Finally, the Celtics commit a turnover on 14.2 percent of possessions, which could fuel Portland in transition.
