Who was the most self-destructive in their careers?

[El Kabong]

Ike Ibeabuchi, he was a title holder when he got in trouble....he at the very least had fights vs Lewis and Holyfield ahead of him, maybe Tyson as well, who knows.

Johnny Tapia I mean how could he NOT be listed here?

'Kid Dynamite' Danny Romero is another than never reached his potential

Kelly Pavlik, alcohol abuse did a number on him

Meldrick Taylor, super slick boxer but just CHOSE to go to war, really hurt his career.

Any number of drugged out wash-ups especially heavyweights of the late 80's early 90's

Ike was railroaded by a lying hooker in Vegas & a suspiciously corrupt justice system
Any man kept heavily sedated for 14 months before going to trial because they were apparently "scared of what he MIGHT do"is going to develop mental problems

Yeah? Well I guess the OTHER lying hooker/escort with a similar story was ALSO trying to railroad him. As for his mental stability, how's about the time when Ike abducted the child he had with a former girlfriend and drove head first into a concrete abutment so now the child will never walk normally and suffered numerous injuries. Cedrick Kushner tried wining and dining an HBO Boxing exec with Ike at a fancy restaurant when all of a sudden Ike brandishes a large knife and starts yelling 'They knew it! They knew it! The belts belong to me! Why don't they just give them back?'
