Most un-dedicated fighters?

[ElTerribleMorales]

another fighter that comes to mind is Juanma Lopez, who cut his career short by blowing up in weight between fights and then not full dedicating himself to his craft and only relying on his power that didn't make up for his punch resistance that faded quickly due to his bad training habits and blows taken in fights

Not-Dedicated

* James 'Buster' Douglas always had 'motivational' issues.

* Joe Louis went thru spells of 'lackadaisical efforts'.

* Ron Lyle was inherently lazy at periods during his career.

* Gerry Cooney was lacking in intestinal fortitude.

* Max Baer was a funny sort, who got by on his punching power alone.

* Ingemar Johansson was 'A Playboy'.

* Ray Mercer just didn't like to train.

Corrie Sanders....dude could have been GREAT if he was not on the golf course so often. The power he had, the speed, he was very impressive in those regards.

"I agree. James Toney just doesn't know how to walk away from a Buffet table."

Riddick Bowe

[ElTerribleMorales]

this will seem like blasphemy, but at one point Arturo Gatti? I mean he himself said that there was a stage in his career (I think prior to his fights against Ward) that he would hardly train and that he spent too much time out partying and drinking
