GGG showed he could land more punches on his opponent while backing up also and Frazier was a clever puncher who had a great defense.
Tommy Hearns proved he could outjab Benitez and Ray L. despite being outdone by Ray in the pocket eventually, something nobody thout Leonard could do at the time even after he did so well in the pocket against Duran in their first epic clash where Ray proved for the first time how tough and Durable he was, not just the flashy, fast fighter tag he had at tat time.
Nobody thought Ray could do well with Hearns in the pocket at the time? Hearns wasn't exactly considered an infighter you know.
but Mark only has 1 reference for boxing; a 1996 "The RING" magazine and it did not explain that about Hearns. So, who knew?
