fighters with tons of talent, and zero dedication

[Dynamite Kid]

Nunn

Michael Nunn he did win another World Title aftr the Toney fight but he was still involved in crime and drugs etc , so ive heard anyway

very very talented fighter none the less who never achieved what he should have through lack of dedication

[Gareth Ivanovic]

Hassim Rahman. In his one fight against Sykes he looked way out of shape and didn't seem to take his profession seriously.

[Mishra100]

Honestly? Michael Spinks comes to my mind. There was NO reason for him to quit after being KOed by Tyson.

[ZOSOOSOZ]

rid**** bowe comes to mind.name any you know about..

This is the first name that came to mind.

Big Daddy was amazing to watch. It's too bad he couldn't find some way to be consistently disciplined and dedicated.
