If Toney, Hatton, Vargas, etc etc. Perform in the ring, who are we to criticize them in there personal life for how big they do or dont get ?
Because it can have an affect on their performance in the ring, or how long they will be able to perform at a high level in the ring. Most guys can't be like Duran.
It can take years off of a fighter's career for them to continually go up and down in weight and mistreat their bodies. It is, of course, their choice whether they want to take care of themselves or not.
