Why doesn't Mayweather fights until he loses?

[Allucard]

Because he's smarter than boxing and won't let boxing retire him, he will retire boxing instead. He has proved himself over and over but fact is: Young and apparently good fighters are continuosly emmerging (good for boxing) and is certain that if you fight them continuosly you will lose as your body wears with each fight. People here making threads like "Mayweather fight him, him, him, him and him too" are not really fans of any fighter or boxing. They are kids who just want to see a fighter (in this case Mayweather) being possibly killed in a ring...

That's specially clear when you see Hoya's greatest fans becoming Hatton's biggest fans in one year.

How silly of people wanting to see the self proclaimed "greatest fighter that ever lived" prove it. How silly of people wanting to see the "best WW in the world," I don't know, maybe fight the best WWs in the world.

I think he will fight 1 fight away from loosing if you get my point. I can see him fighting Cotto, Williams and then a rematch with De La Hoya. Before retiring. 3 fights he should win. But then im sure by the time he retires, he won't be the same guy fighting today, because age would catch up with him. And a new young champion, e.g the next Cotto, could take him down. But at that stage he would retire before that fight.

Sorry to confuse you.
