He's one of very few people -- Voulgaris estimates there may be as few as four or five -- who have achieved a high level of success betting full-time on the NBA.
And he does very well at it. "In the last eight years," he explains, "the 2004-2005 season was the only year where I didn't turn a nice profit, and I lost very small."
His approach is intensively evidence-based. He has his own massive database that would be the envy of any stat geek. For instance: Given two line-ups of players on the floor, his database does, he says, a good job of predicting which players will guard each other. The database also tracks the tendencies of individual referees, and factors all that and much more into forecasts. Voulgaris also watches close to 1,000 games a year.
