Top 76ers vs. Celtics predictions

After 10,000 simulations of 76ers vs. Celtics, SportsLine’s model is going Under on the total (217.5). The Under has hit in each of their last four head-to-head matchups. The Under has also hit in nine of the last 11 76ers games, and in seven of the last 11 Celtics games. The Under has also cleared in 53 of the last 83 Boston games when the line is over 203 points.

The SportsLine model is projecting the 76ers to have just three players scoring 14.9 points or more, led by Tyrese Maxey’s 25.5 points. Jaylen Brown is projected to lead the Celtics with 28.4 points scored, but only three Boston players will score 15 or more points. The teams are projected to combine for 212 total points, making it a great selection for anybody targeting NBA parlay betting.
