Re: julio senior chavez vs kostya
No-one ever put JC Sr down the way Tszyu did but he was 38 at the time.
JC Sr had the best chin of any fighter I've seen and King Kostya would not have dropped a prime Sr irrespective of how hard he hit him.
A good chin stops good hitting.
JC Jr takes big punishment against GGG early but if he survives he may give some of it back late. As would have happened if a prime Tszyu fought a prime JC Sr.
The big difference in terms of drawing analogies is that while GGG may be comparable in ability to King Kostya, it's a big stretch to say JC Jr is comparable in ability to JC Sr.
