Floyd Mayweather Jr., 36, will step into the ring Saturday night to fight Roberto Guerrero for the first time in a year. Mayweather says he is a more mature fighter. Two months in prison — spent doing pushups in solitary confinement in a small cell in Las Vegas — might have aided the growing-up process. Mayweather acknowledged his last fight, a 12-round decision over Miguel Cotto, wasn’t his best, another sign the world's highest paid athlete is coming of age.
Mayweather, the pound-for-pound best fighter in the world, is also a champion businessman, and he realized to sell this fight — $69.95 on pay-per-view — he had to take the high road during the prefight hype, in which Guerrero’s father and trainer accused Mayweather of being a woman beater.
