Before making any Heat vs. Celtics picks, you NEED to check out the NBA predictions from the SportsLine Projection Model.

The SportsLine Projection Model simulates every NBA game 10,000 times and has returned well over $10,000 in profit on its top-rated NBA picks over the past three-plus seasons.

The model knows the Heat are tremendous on both ends of the floor. Miami is giving up fewer than 1.08 points per possession on defense, and the offense is lighting it up on a nightly basis. The Heat are scoring 112.3 points per 100 possessions, a top-five mark in the NBA, and Miami is No. 4 in the NBA in shooting efficiency. Miami leads the NBA in 3-point accuracy at 37.7 percent, with top-six rankings in assists and assist percentage. The Heat also have a top-five offensive rebound rate, and Miami puts constant pressure on the defense.

The model also knows the Celtics are well-equipped on defense. Boston is No. 4 in the NBA in defensive efficiency, allowing only 1.06 points per possession. The Celtics are No. 2 in the league in field-goal percentage allowed at 43.7 percent, and no team is allowing fewer assists (21.7 per game) than Boston. The Celtics are also near the top of the NBA in points allowed in the paint, free throw prevention, blocked shots and second-chance points allowed.
