Dillashaw was on track to become the greatest UFC bantamweight fighter ever. However, he tarnished his record when he tested positive for EPO in 2019 after fighting Henry Cejudo (via The Athletic).
His former teammate Cody Garbrandt accused him of doping throughout his career. Unfortunately, Dillashaw’s entire career received an asterisk after this. It was his fault because PED use is unforgivable in combat sports.
Few people achieved as much in the sport of baseball as Rose. He had a Hall of Fame-worthy career befor enjoying some success as a manager. But then a gambling scandal tarnished his legacy.
MLB has a zero-tolerance policy when it comes to gambling and this costs Rose dearly. It also ended his dream of entering the Hall of Fame. Some fans believe that they should allow him in but others think he made his bed (via History).
There was a time when Haynesworth was one of the top defensive players in the league. Fans saw his dark side when he brutally stomped on Andre Gurode in 2007. Then, he joined the Redskins.
Haynesworth became one of the highest-paid players ever but immediately checked out after receiving the lucrative contract. He failed to earn his money by delivering on the field and he ballooned in weight (via The Athletic).
U.S. athletes constantly overshadow Canada’s sporting heroes. That’s why Johnson’s Olympic success meant so much to the nation. They finally had a true sporting icon after his exploits in Los Angeles, but then he tested positive for PEDs.

Mourinho instantly became Europe’s hottest young coach after he won the Champion’s League with Porto in 2004. Then the self-professed “Special One” moved to Chelsea and achieved even more success as one of Portugal’s heroes.

Belichick is the most successful coach in NFL history, but that doesn’t mean people like him. In the beginning, he won respect because he brought the Patriots to the top and maintained dominance.
But Belichick is also a notorious cheater. He infamously videotaped the Jets’ practice facility to film their defensive signals. Belichick puts winning above anything else no matter the cost. Spygate was a stain on the sport (via SBJ).
Owen was one of the top young strikers in Europe during his time with Liverpool. He famously scored a mesmerizing goal against Argentina when he was 18. Then he moved to Real Madrid but it didn’t work out (via Sky Sports).

It’s scandalous that they thought that they could get away with this. Spain competed in basketball at the 2000 Paralympics. They claimed that their team members had intellectual disabilities. But a whistleblower revealed the truth.
None of their players had any disabilities at all. The Spanish federation wanted their team to receive more sponsorships so they lied to the world. It became a massive scandal because this was a disgraceful thing to do (via InsideTheGames).
Baffert is one of the most successful trainers in American horse racing. His horse, Medina Spirit, won the Kentucky Derby in 2022 but then a controversy emerged. The horse tested positive for a banned substance and they received suspensions.

Brady is the greatest quarterback in NFL history. He entered America’s pantheon of sporting heroes when he won his first Super Bowl as a sixth-round selection.

Liverpool loves their heroes but Suarez is one of the most polarizing in their recent history. He’s arguably their most talented player ever but opposing fans hated him. That’s because of multiple incidents of biting and even racism.

We’ve mostly avoided putting teams on this list but it’s difficult to single out an individual here. The Astros won the World Series in 2017 and became heroes. But they brought their city into disrepute with a major sign-stealing scandal.
They cheated regularly through the year on their way to glory. In the end, MLB sanctioned their coach and G.M. but the players escaped without penalties. This was a shambles because the athletes led the cheating, not the coaches (via NPR).
Who better to include from baseball’s infamous Steroid Era than Bonds because he broke the home run record? When the dust settled, he was no longer one of baseball’s biggest heroes.
The Steroid Era is complex because it was one of the most exciting times in the sport. But the level of cheating was ludicrous. Meanwhile, Bonds may never make the Hall of Fame because everyone knows he took PEDs (via The Ringer).
Women and young girls want sporting heroes that they can relate to. It appeared that Jones was perfect because she won gold against the odds in the Olympics in 2000. But she became a key part of the BALCO scandal and lost her medals.

In recent years, Saudi Arabia made a massive push to host sports events. That’s because it wants to sports wash its image and change how people perceive the country. One of these events is their breakaway golf league (via The Guardian).

Woods enjoyed phenomenal success in the 2000s before his sordid sex scandal. The golfer was one of the most clean-cut sports heroes but it instantly changed. After a drunken crash, dozens of women accused him of extramarital affairs.

But Armstrong ruined everything when news of his doping emerged. This occurred on a grand scale and World Cycling scrubbed his biggest wins from the record books. Meanwhile, Armstrong lost millions of dollars in endorsements (via Reuters).
Larson is one of NASCAR’s top drivers but also a controversial figure because of an odd incident. He was participating in an online racing game when he dropped a racial slur. Larson didn’t realize that his microphone was live.

Davis is a brilliant boxer, but he’s also a thug. The Baltimore native burst onto the scene as Floyd Mayweather’s protege. However, he tarnished his image with multiple legal issues. First, there was a public display of domestic violence (via TMZ).
Then his Lamborghini was involved in a hit and run in 2021. Meanwhile, “Tank” had several street fights and can’t stay out of trouble. Some sports stars are heroes but Davis simply isn’t a good role model.
One of France’s greatest-ever players, Zidane was a true superstar. He decided that the World Cup in 2006 would be his final tournament. They made it to the Final against Italy but it ended in tears for Zizou. This was a notorious moment.
He head-butted Marco Materazzi after the Italian insulted his sister. This moment cost his team dearly. Italy had an inferior squad but dragged France to the penalty shootout. Then they won the game as Zidane sat and watched (via NZHerald).
Watson was one of the few good things that the Texans had going for them. The quarterback was a star but things came to a head in 2021 when he demanded to leave. Then a sexual harassment scandal rocked the NFL.

McGregor was arguably the UFC’s first mainstream superstar. The Irishman was a two-weight champion and had incredible charisma. But he went from hero to villain with his antics outside of the cage when punched an old man in a bar (via Daily Mail).
Meanwhile, he became involved in multiple unsavory legal issues. These included sexual assault allegations and multiple speeding offenses. A woman also accused him of impregnating her at a party in Liverpool.
Hernandez and Rob Gronkowski struck fear into the hearts of opposition teams. The Patriots duo were two of the best tight ends in the sport. However, Hernandez never achieved his full potential because he was a murderer.
