We're not talking about age here, but we might as well be. Experience translates to maturity in this case, and Argentina's Martinez is at the perfect point of equilibrium between his 37 years of age and 15 years of ring experience. He's old enough to know it all but still young enough to carry it out between the ropes. Chavez is a nine-year pro (seasoned for a 26-year-old), but a shaky level of opposition in his early days and a taste for custom-made opponents have deprived him of the tougher, more diverse challenges that might have given him more clout in this category.
