Whitaker could do real damage with his left hand. Obviously he wasn't the most heavy handed guy, but he could do serious damage with his left when he got leverage on it, and also because of his placement and accuracy. He briefly rocked Chavez in the 8th round of their fight, unified the LW belts with one left hand against Nazario, all but ended the Lomeli fight with one left, turned the Hurtado fight around with his left hand bombs.
