Boxers who threw it all away by going to jail.
This came to my mind because of the horrible and sad events leading to the death of Edwin Valero's wife.
Some guys I can think of of the top of my head are Tyson, Ike Ibeabuchi, Tony Ayala Jr., Harry Simon and Ricardo Williams.
Any other guys that showed immense talent and got derailed by jail time? When I say immense talent Im talking about guys that looked like they could be the man at a division for a long time or a future superstar.
