Will PBF retire undefeated?

[The Rookie Fan]

It is a very hard thing to do. Think it has only been done twice in history. (I'm not counting Sven Otkey)

And the guys who did it only fought in one weight class. For a multidivision champion to retire undefeated would truelly be amazing. But I believe the money and the fame will keep bringing him back till he either looses or comes very close to loosing.

Don't know who will do it though.

4 have retired undefeated as champions Sven Ottke, Ji Won Kim, Ricardo Lopez, Rocky Marciano. And as for the question in this thread yes Mayweather will retire undefeated.

Ji Won Kim? Damn, what archives did you havo to get into to find him? LOL never heard of that guy. Was he good?
