U.S. Attorney for the Eastern District of Pennsylvania, David Metcalf, described the scheme as “massive” and an “international criminal conspiracy.”

“It enveloped the world of college basketball,” he said at a news conference in Philadelphia.

The gamblers often placed bets and then recruited players with the promise of sums in the tens of thousands if they could purposely underperform in their games. If the players properly underperformed, the gamblers would win their bets, often against the teams of the bribed players.

“For example, if a team was favored to lose by 4 points, the player would receive a bribe to underperform so that his team would lose by more than that,” Metcalf said.

Several prominent schools’ teams games were involved in the scheme: Abilene Christian, Alabama State, Butler, DePaul, Duquesne, East Carolina, Florida Atlantic, Fordham, Georgetown, Kennesaw State, Kent State, La Salle, McNeese State, Nicholls State, Ohio University, St. Louis University, St. John’s, SUNY Buffalo, Tulane, and Western Michigan University.

The betting scheme began with bets placed on Chinese Basketball Association games. Former Chicago Bulls player Antonio Blakeney allegedly colluded with Marvis Fairley and Shane Hennen to fix CBA games.

“The scheme proved lucrative,” Metcalf said. “Mr. Hennen, we allege, texted a confederate that the only things certain in life were ‘death, taxes, and Chinese basketball.’”

The betting scheme was then moved to the United States, and conspirators began recruiting college basketball players to participate.

“They picked these men because they were well connected in the world of college basketball,” Metcalf said. “They knew the players, many of them were players themselves, they were alumni, they were trainers, they were recruiters, they were networkers, they were people of influence, and because of that influence, they added gravitas and legitimacy to the scheme.”

NCAA President Charlie Baker was aware of the charges, and the organization had already investigated, or was investigating, almost all the teams named.

“The pattern of college basketball game integrity conduct revealed by law enforcement today is not entirely new information to the NCAA,” Baker said in a statement.

The college basketball betting scheme comes after the NCAA banned three prominent Division 1 basketball players for participating in “sports-betting related game manipulation.”
