http://sport.guardian.co.uk/boxing/theobserver/story/0,,2220425,00.html The article is an interview with Mayweather Sr. So how reliable it is can be questioned given the source. Mentions PBF's background, family conflicts, violent private life (domestic assault charges which he did plead guilty to) etc.
two words for all mayweathers out there: "NO COMMENT". I'm taken aback at how willing this family is to air out their business to the media.
