The game in question took place on March 23, 2023, when Rozier was a member of the Charlotte Hornets. The betting on Rozier was strange enough that day to raise alarms at U.S. Integrity, a firm that works with sports entities, gambling operators and government agencies to monitor betting markets for suspicious activity.
U.S. Integrity notified sportsbooks—and the NBA—that unusual wagers were coming in on Rozier failing to meet certain statistical benchmarks, such as the total number of points or rebounds he would record in the game. Some of the sportsbooks stopped accepting bets on Rozier’s stats that day, people familiar with the matter said.
Rozier boxscore on March 23, 2023:
- 5 points 2 assists 4 rebounds
Rozier season average
- 23 points 6.6 assist 4 rebounds
This was so blatant it was easily flagged. I'm sure there are tons of players being more subtle and getting away with it.
To think that gambling isn't going to affect players is about as naive to think there are no PEDs in pro sports.
