Great punches no doubt but you've got to think only 1 out of those 3 clips were finishing shots. Just imagine Rocky Marciano landed a clean shot to the chin like that, Mike hit hard but Marciano was truly devastating. Boyd weighed in at 198lb, over 20lb lighter than Tyson. Ribalta was 211lb, 2lb lighter than Tyson. Ferguson weighed 212lb, 5lb lighter than Tyson. Boyd could have carried on, just imagine Marciano hitting an opponent who weighed 20lb lighter than himself with one of his best punches, he would be doing time for murder!
