Before making any Celtics vs. Heat 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 33 NBA selections, Cimini is 22-11, returning almost $1,000 to $100 players. He is also on an amazing 35-16-1 run with his last 52 against-the-spread picks involving the Celtics, returning $1,648 to $100 players.

Cimini knows the Celtics are dangerous in many ways. Boston is out-scoring Miami by 7.7 points per 100 possessions in the series, scoring nearly 1.16 points per possession in the process. The Celtics led the NBA in defensive rating during the regular season, and Boston boasts a 60.1 percent true shooting against Miami. The Celtics are also securing more than 30 percent of their own missed shots, helping to maintain an advantage in the possession battle.

He also knows the Heat have a potent defense. Miami is giving up fewer than 1.08 points per possession in the playoffs, and havoc creation is a big reason. The Heat are creating 19 points per game off turnovers, an elite figure, and Miami is forcing a turnover on 16.1 percent of defensive possessions in the series against Boston. Miami also walls off the rim, leading the NBA in points allowed in the paint during the regular season and giving up only 38.0 points in the paint per game during the playoff run.

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.
