I remember after Lewis vs Holyfield 1 Don Turner said Lennox Lewis was the best in the world at fighting tall ...which fighters in history were the best at using their height and reach to their advantage?
Along with Hearns and Monzon. Add Arguello and Danny Lopez. Both were tall for their weight class, both could fight "tall" but seemed to favor inside.
Bob Foster comes to mind. He was 6'4 which was huge for a Light Heavyweight back in the same day weigh in era. Hell, it's tall for nowadays as well.
Lets see. Milton Mccroy. Hearns of course. Genaro Hernandez- classy boxer even classier person. De La Hoya. Mark Breland at times. Alexis Arguello. While not a fan of his Maske fought tall. Michael Nunn at times although he lingered on the inside at times too much.
