That could be a big step for American athletics as more sports leagues now grapple with legalized betting – and with the tendency to see fans as valuable gamblers rather than as valued spectators. Until now, regulation and tight enforcement has been the default approach. Vast electronic systems are in place to catch cheating. Players are assumed to be prone to corruption. If the NBA now moves to enhance the moral dignity of players, enabling them to better resist gambling interests based on principles, that would be a mental sea change and perhaps better ensure the sport’s integrity.
