Recently, the University of Michigan football program was caught up in controversy over allegations of illegal sign stealing. An NCAA investigation is underway into claims that since 2021, staffer Connor Stallions bought tickets to rival teams’ games to film and decode their hand signals for a competitive advantage.
Sign stealing is not an isolated incident in sports; it’s a recurring issue. In recent years, several top professional teams across baseball and football have faced penalties for similar espionage, including the MLB’s Red Sox and Astros as well as the NFL’s Patriots. Although these high-profile cases are among the few that have been formally exposed and disciplined, experts believe that many more teams are likely involved in covert operations to decipher their opponents’ playcalling codes. (Here are the 17 most talked-about corruption scandals in sports history.)
Sports scandals range from questionable on-field strategies to egregious off-field behavior. While many controversies involve cheating and banned substance abuse that skew the fairness of the game, numerous infamous incidents also stem from athletes’ actions outside the spotlight.
Some scandals even involve coaches and trainers who have faced accusations of physical or sexual abuse of athletes in their care. Sports executives have also been involved in controversy, with some facing charges related to money laundering and racketeering. Even governments are involved in sports scandals, such as state-sponsored doping programs aimed at artificially enhancing Olympic performances, has triggered international investigations and widespread condemnation.
To create a list of the most significant sports scandals, 24/7 Tempo reviewed various online sources specializing in sports news and history. We selected cases based on their impact and the extent of unethical conduct involved, focusing on those that had a large effect on the public.
