Why the Celtics can cover

Boston has a big edge on the wings in this matchup, with Jayson Tatum and Jaylen Brown performing at a high level. Tatum leads the team with 25.7 points per game, and he adds 7.1 rebounds per contest and high-end defense. Brown is dynamic offensively, maintaining strong efficiency on the way to 24.3 points and 5.8 rebounds per game. That duo helps the Celtics to be above-average on both ends of the floor, and Portland has a few dire weaknesses to exploit. 

Offensively, the Blazers are potent, but Portland is just 28th in the NBA in 2-point shooting, making only 50.4 percent of its shots inside the 3-point arc. Portland also lands last in the NBA in assists, producing just 20.3 per game. On the defensive side, Portland ranks 29th in the NBA in overall efficiency, allowing 1.16 points per possession. The Blazers are also 29th in 2-point defense, with opponents converting 54.9 percent of their attempts.

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.
