22. Pete Rose
If you didn’t know about Rose’s coaching history, you’d think that his absence from baseball’s Hall of Fame is a travesty. MLB’s all-time leader in hits won an outrageous number of accolades. The three-time World Series champion led the Cincinnati Reds for three seasons. Furthermore, the 17-time All-Star was a decent manager. But then his betting scandal emerged and ruined his legacy.

Now serving a lifetime ban from baseball, the three-time Gold Glove winner explained his reasons for betting in his autobiography. He said he suffered from a condition called Oppositional Defiant Disorder. But the problem was that this was a childhood disease and not something that adults get. As justifications go, this one was incredibly weak. It’s a pity that Rose stained his reputation forever.
