What the 76ers can cover

Philadelphia's offense is impressive in its efficiency, and the 76ers have been even better when the roster is approaching full strength. Philadelphia is scoring more than 1.1 points per possession this season, shooting nearly 46 percent from the floor and 36 percent from three-point distance. The 76ers also make gains in ball security, committing only 12.6 turnovers per game, and Philadelphia doesn't beat itself at the free throw line in making 81.7 percent of attempts. 

Boston is a bottom-five team in free throw prevention, and that could swing things to Philadelphia on the margins. On the opposite side, the 76ers are above-average in free throw prevention, and well above-average in blocked shots (5.9 per game) and steals (8.1 per game). Boston is also just 25th in the NBA in shooting efficiency this season.

Why the Celtics can cover

Of the four core units involved in this game, Boston's defense is the best. The Celtics are allowing only 104.9 points per 100 possessions this season, ranking in the top five of the NBA in defensive rating. Boston is limiting opponents to 43.5 percent shooting, and opponents are producing just 21.5 assists per game against the Celtics. Ime Udoka's team is also in the top eight of the NBA in defensive rebounding, grabbing 74.7 percent of available rebounds after missed shots, and Boston is No. 3 in the league in second-chance points allowed (11.4 per game). 

The Celtics also excel in making life difficult on opponents and making the opposition earn baskets in difficult ways. Boston is in the top 10 of the league in fast break points allowed (11.6 per game) and No. 6 in the league in points allowed in the paint (43.0 per game). The Celtics also protect the rim at a high level with 5.6 blocked shots per game, and the 76ers are currently in the bottom five of the NBA in offensive rebound rate at 24.4 percent this season.
