The Algo’s Behind NBA Betting

The algo’s behind NBA betting.
ESPN on Bob Voulgaris, a bettor who is using algo to place NBA bets. 
By 2009, once they’d added this mysterious additional model to Ewing’s inner workings -- version 2.0 -- they started making bets based on the scores it produced after the All-Star break. “We just, like, crushed the second half of the season,” Voulgaris says. Since then, as each subsequent season has passed, Voulgaris’ confidence in Ewing has increased. So too has the frequency of his wagering. In a season, he now regularly puts down well over 1,000 individual bets. “I mean, I don’t want to sit here and brag,” he says. “But this is literally, like, the greatest thing ever when it comes to sports betting.”
Despite it all, Voulgaris faces the same issue that all sharps face: the sustainability of his edge, no matter how sophisticated the model that produces it. When he returned to gambling for the 2010-11 season, Voulgaris says Ewing clocked an ROI of more than 6 percent. By 2011-12, it had fallen to 5.14 percent.
