NBA starts review of policies after gambling-related arrests of player and head coach

The NBA, in reaction to the arrests of Miami guard Terry Rozier and Portland coach Chauncey Billups last week for their alleged role in gambling schemes, has started a review of how the league can protect not just the integrity of the game but its players and coaches as well.

The league made those revelations in a memo sent to all 30 teams, a copy of which was obtained by The Associated Press.

"Given the spread of legal betting to the majority of U.S. states, the recurrence of integrity issues across sports, and the emergence of novel betting formats and markets, this is an opportune time to carefully reassess how sports betting should be regulated and how sports leagues can best protect themselves, their players, and their fans," read the memo, sent by the NBA's legal department.

A pair of indictments were unsealed last week and nearly three dozen people, most notably, Billups and Rozier, were arrested by federal officials.

Rozier was arrested because federal officials allege he conspired with associates to help them win bets based on his statistical performance in a game played when he was with Charlotte on March 23, 2023. The charges are like what former Toronto player Jontay Porter faced before he was banned from the league by commissioner Adam Silver in 2024.

Sportsbooks detected unusual patterns of wagers on the Charlotte game in question — prop bets involving Rozier were flagged and immediately brought to the NBA's attention — and the league probed the matter but did not find enough evidence to conclude that Rozier broke any rules.

"While the unusual betting on Terry Rozier's ‘unders’ in the March 2023 game was detected in real time because the bets were placed legally, we believe there is more that can be done
