Pete Rose
Rose was one of the top baseball players of his era before he embarked on a managing career. Things were going well in that respect too before a gambling scandal emerged. MLB has a zero-tolerance policy toward gambling abuse because of historic issues that tainted the sport. They banned Rose from baseball and blocked his entry into the Hall of Fame.

However, Rose maintains his innocence throughout the investigation. In the end, he accepted a deal to plead guilty but he resents baseball’s top brass. Furthermore, one of the sport’s long-term dramas continues to rumble on. Many people think MLB should give him a second chance and that he deserves a spot in Cooperstown (via History).
