ie. They scored an all-time classic/great KO and in another fight were the KO'd by an absolute classic/great KO punch. The two that come to mind for me are : Don Curry (KO2 McCrory and LKO5 McCallum) Jersey Joe Walcott (KO7 Charles and LKO13 Marciano)
True, I think he's KO loss to Barkley was even more "classic". Hagler brawled him and battered him before the final icing, Barkley just turned the whole script on its head with one punch !
And Rahman was on the 'wrong side' of classic KO not once. Maskaev 1 was classic, too. Maskaev 2 was going to be classic, too, when Rahman was staggering in corner, reading to fall out of the ring once again. Nagy saved poor Hasim from another classic KO.:deal
