This stuff has always happened in boxing. Its hard for a great boxer to give up the sport before its to late. Boxing is an individual sport, all the lights are focused on you and your opponent. Across from the ring is a guy that wants to rip your head off just as much as you do. One man leaves standing with his hand raised as the better man. Its a great sport and hard to give up plus its very lucrative. If Barrera loses it will just be another name on a long list of fighters that just couldn't walk away.
