Mayweather vs Guerrero: Boxing Champ Looks Toward Retirement Leading Up To Guerrero Fight

Floyd Mayweather Jr.'s welterweight title defense against Robert "The Ghost" Guerrero on Saturday night at the MGM Grand Garden Arena kicks off what is believed to be his exit strategy as an active fighter. The match is the start of the mega deal that he signed earlier this year with Showtime/CBS - dumping career-long TV home HBO - that calls for up to six fights over the next 30 months.
