Boxing is a sport in which a fighter can rise to the top in meteoric fashion and then crash just as quickly.
The nature of the game is such that few fighters are ever able to attain and maintain a level of success that keeps them at the top of the sport.
Those who do are deserving of the term legends.
But far too often these same men are the last to realize that their time has passed.
The jab isn't as quick anymore. The reflexes are a half-step slower. The right hook that used to end fights just can't get there anymore.
And sometimes due to self-delusion, or unfortunately in some cases due to financial problems, these fighters continue to plod on and do unnecessary damage to their health and legacy.
These men fit that bill perfectly as we examine the 10 fighters who didn't know when to quit.
