Top Celtics vs. Spurs predictions

After 10,000 simulations of Spurs vs. Celtics, SportsLine's model is going Over on the total (222.5). These two have frequently engaged in high-scoring affairs in Texas as the Over has been reached in seven of their last 10 matchups in San Antonio. The last of those came in March 2025 and saw 232 combined points scored. Speaking of playing in San Antonio, the total has been surpassed in each of the Spurs last two home games, and the Over is 5-2 over San Antonio's last seven home contests.

Few teams are as efficient inside the arc as the Spurs, who rank second in 2-point percentage, while few squads can match up with Boston on the perimeter. The Celtics are third in made 3-pointers per game and average the fewest turnovers per game. With the proficiency of these two offenses, both defenses are projected to allow at least 4 more points than their season average. The Over is surpassed in 61% of simulations.
