The NBA has started a review to protect the integrity of the game, players, and coaches following the arrests of Miami guard Terry Rozier and Portland coach Chauncey Billups. They were allegedly involved in gambling schemes. The league sent a memo to all teams, highlighting the need to reassess sports betting regulations. Nearly three dozen people, including Rozier and Billups, were arrested last week. The NBA is focusing on injury reports, which can be exploited by bettors. The league seeks to ensure players and coaches understand the risks of gambling and is seeking input from teams on how to proceed.
