Before making any Heat vs. Celtics picks, you NEED to check out the NBA predictions from SportsLine expert Zack Cimini.

A Las Vegas handicapper who's never afraid to buck conventional wisdom, Cimini excels in multiple sports. Over the past 34 NBA selections, Cimini is 23-11, returning almost $1,100 to $100 players. He is also on an amazing 36-16-1 run with his last 53 against-the-spread picks involving the Celtics, returning $1,748 to $100 players.

Cimini knows the Heat have a stout defense. Miami is giving up 37.2 points in the paint per game in the series after leading the NBA in the same metric during the regular season. The Heat are also forcing a turnover on more than 16 percent of possessions, including 8.8 steals per game. Miami is also the superior rebounding team on the whole, which could lead to extra possessions to boost efficiency.

He also knows the Celtics are dominating the series from a statistical standpoint. Boston is out-scoring Miami by 8.7 points per 100 possessions, including back-to-back blowout wins. The Celtics are taking 29.2 free throw attempts per game in the series, and the team's defense is impressive. Boston is yielding just 1.04 points per possession, and Miami is shooting only 40.7 percent from the field in the conference finals. 

Now, Cimini has set his sights on Heat vs. Celtics. We can tell you he is leaning over the total, and he's isolated a critical x-factor that makes one side hit HARD! You ABSOLUTELY need to see what he has to say before locking in any NBA picks.
