Not long ago, the University of Michigan football program found itself embroiled in controversy amid accusations of illegal sign stealing. An NCAA investigation has been opened into allegations that since 2021, the Wolverines staffer Connor Stallions purchased tickets to opponents’ games to film and decipher their hand signals for competitive advantage.
Unfortunately, sign stealing schemes are far from an isolated incident in sports. Several elite professional teams across baseball and football have been caught and penalized for similar espionage in recent years, including the MLB’s Red Sox and Astros as well as the NFL’s Patriots. And while these powerhouses represent some of the few formally caught and disciplined cases, experts suspect dozens more teams likely engage in covert operations to crack opponents’ playcalling codes. (These are the 17 most talked-about corruption scandals in sports history.)
Sports scandals run the gamut from questionable on-field tactics to reprehensible off-field conduct. Several controversies center on cheating maneuvers and banned substance abuse that unfairly tilt the game. But plenty of other notorious incidents stem from athletes’ activities beyond the bright lights.
And it’s not just players embroiled in scandalous disgrace. Coaches and trainers alike have faced accusations of physically or sexually abusing athletes under their supervision. Sports executives have sparked outcry through indictments tied to money laundering and racketeering ploys. Even governments stir suspicion – state-sponsored doping programs to unlawfully boost Olympic medal counts, for example, continue to unleash global probes and strong rebukes.
To compile a list of history’s most notable sports scandals, 24/7 Tempo consulted several online sources focused on sports news and history. To measure the size of the scandal, we used our editorial discretion to highlight cases that involved unethical conduct or otherwise had a large impact on the general public.
