Betting scandals have been a concern for professional sports leagues for as long as they’ve existed, but a U.S.

The NFL in recent years has doled out several suspensions for player violations of its sports gambling policy, though not many as of late.

NBA coach Chauncey Billups and player Terry Rozier were arrested in a massive illegal gambling scheme involving organized crime families and rigged poker games, the FBI said Thursday.

The arrests of Chauncey Billups and Terry Rozier in the federal investigation into sports betting and illegal gambling called into question how the NBA is working to protect its players from the dark side of the wagering world. And according to Boston Celtics forward Jaylen Brown, the league has not done enough in that regard.
