Why the Celtics can cover

While the Pacers have the league's best offense, the Celtics are also fantastic on that end of the floor. Boston is led by Jayson Tatum, who has scored at least 20 points in seven straight games. He is averaging 27.4 points on a career-best 62.3% true shooting this season, and Tatum adds 8.7 rebounds per contest. Boston is near the top of the league with 1.17 points per possession, and the Celtics are prolific from 3-point range. The Celtics are making 15.6 triples per game, and Boston is in the top three of the league with 57.5% shooting inside the arc. Additionally, this is also an advantageous matchup for Boston against a porous Indiana defense.

The Pacers have the second-worst defensive rating (120.8) in the NBA, and Indiana is dead-last in opponent shooting. That includes 50.4% shooting from the field and 40.0% from 3-point range for Indiana's opponents, and the Pacers are also allowing the most free throw attempts (28.5 per game) in the NBA. Indiana also scuffles on the defensive glass, producing bottom-five marks in defensive rebound rate (68.1%) and second-chance points allowed (16.4 per game). The Pacers are also giving up the most points in the paint (63.0 per game) by a wide margin, and Boston can attack the rim as a result. See which team to pick here.  

Why the Pacers can cover

Indiana has the benefit of home-court advantage in this matchup, and the Pacers have a stellar +7.8 net rating at home this season. Indiana is led by its dynamic offense, leading the NBA in offensive efficiency by a comfortable margin, generating 123.8 points per 100 possessions. 

The Pacers are No. 1 in the league with 51.1% shooting from the field, including a league-best 60.2% mark inside the 3-point arc. Indiana is also in the top five in both 3-point accuracy (38.4%) and 3-pointers (15.0 per game). The Pacers sit atop the league in assists (30.3 per game), fast break points (17.7 per game), and points in the paint (59.9 per game) this season, and Indiana can play freely against a relatively conservative Boston defense. The Celtics are in the bottom five of the league in creating only 12.5 turnovers per game in 2023-24. See which team to pick here.
