Jon Jones
Many UFC fans regard Jones as the greatest fighter in history because of his incredible skills. However, the youngest champion in history has many demons and can’t avoid scandals. He infamously failed multiple drug tests but that’s not the main reason why he’s on this list. His worst moment came in 2015 when he had a notorious hit-and-run incident.

The intoxicated UFC fighter crashed his vehicle into another with a pregnant driver. Jones fled the scene as he tried to avoid the consequences of his actions. In the end, the UFC took the rare step of stripping him of his title. Jones also received 18 months of probation. But he returned and now many people have forgotten about this awful story (via New York Post).
