best jab? i think it depends on how they utilize the jab.. Hearns with his flicker for example, winky's jab, lewis with power in his jab. Oscar, sweet pea..all have differences
Its not Lewis for sure. We see how good his jab was against Mercer, who outboxing him. While Klitschko destroy Mercer. Holmes, Klitschko, De la Hoya.
I think Bernard had a great jab. It was so good that he rarely had to use it. Wlad obviously has a good jab. I was extremely impressed with GGG's jab against Lemieux.
