when you look at the big name guys who are undefeated at the moment.. you have Calzaghe/Pavlik/Cotto.. those are the big names in their respective weight classes, and they all happen to be quiet guys, who shut their mouths and fight.. Even someone like Klitschko is a quiet champion..

When you look at Tyson/RJJ/Mayweather they all made quite a stir in the media, and the current big names have completely different persona's..

makes you wonder if these loud mouths are necessary for boxing to be more successful in the media.
