Why the Suns can cover

Phoenix's offense is very strong, scoring more than 1.1 points per possession, and the Suns are in a favorable position as a result. However, the Suns are even better on defense, and Boston's offense has struggled in key areas this season. Phoenix is No. 3 in the NBA in defensive rating, allowing fewer than 1.04 points per possession, and the Suns are holding opponents to 43.5 percent from the field and 32.9 percent from three-point range. Phoenix is also in the top five in steals (8.6 per game) and assists allowed (22.2 per game), and the Suns are above-average in preventing free throw attempts, allowing only 20.0 per game. 

Boston's offense ranks in the bottom 10 of the NBA in overall efficiency, and the Celtics are No. 23 in the NBA in assists. The Celtics are also just No. 24 in three-point accuracy and No. 23 in field goal accuracy in 2021-22.

Why the Celtics can cover

Boston's defense could benefit from a few shortcomings of the Suns. Phoenix is only No. 27 in the NBA in offensive rebound rate and No. 25 in the NBA in free throw attempts per game. From there, the Celtics are in the top ten in allowing 107.5 points per 100 possessions, and Boston ranks in the top six of the league in assists allowed (21.8 per game) and blocked shots (5.6 per game). 

Boston is very good on the defensive glass, securing more than 73 percent of available rebounds, and the Celtics create more than 14 turnovers per game. Opponents are shooting just 44.2 percent from the floor, and Boston is giving up only 42.9 points per game in the paint and 12.3 second-chance points per game. Boston's offense is in the top five in free throw attempt rate and free throw accuracy, with above-average ball security that should help in maintaining an edge in the possession battle.
