Prime Evander Holyfield = David Haye. Remember Bert Cooper almost Ko'd Holyfield. So people were probably saying Holyfield had a glass chin too at that point.
a glass chin means youve been knocked down by glancing blows....or repeat ko losses....holyfield almost had his head knocked off by that punch....bert cooper would have kod anyone in the division that night with that punch.....
personally I thought holyfield beat valuev by a wide ud imagine what he would have done to valuev in his prime.
