Over 15 rounds, who would you pick? Gans looks fantastic on film. Personally, I believe he's the third most dangerous lightweight H2H after Duran and Whitaker. However, Canzoneri had one of the best chins in history, with only one of his losses coming by knockout. I would favor Gans, because of his superior defense and the fact that I don't think he would gas out and allow Canzoneri to take control in 15.
