The story was an investigation into a high-profile sports gambling scandal that came to light 2007, when federal investigators brought to light that NBA referee Tim Donaghy had been wagering on his own games. Previously, both Donaghy and the NBA had denied that Donaghy had deliberately made calls on the court in order to alter the game’s score and win bets. We found fresh evidence—both from human sources as well as new data analysis of Donaghy’s foul calls during his final NBA season—showing that he did. For the first time, the story also revealed the identities of the underground professional gamblers who were behind the fix. With sports gambling in the U.S. becoming legalized after decades of prohibition, the story showed that major U.S. professional sports in the modern era are not invulnerable to gambler-induced manipulation.
