But he had a significantly shorter reach. By your theory or things, that should not be possible. Nothing to do with anything. The best guys with the short reach, like Marciano and Tyson, are often the most aggressive, because they force themselves inside. Yes, he a other skills that compensate for his poor reach. That is MY point. Bulk is not the only attribute any more than reach is. In fact, Briedis challenged Chisora to his face after the first Jai fight, and Chisora turned him down. A boxer-puncher like Briedis would have a chance against a lot of guys with better than 75 inch reach, and obviously so.
Tyson was an exception, he shouldn`t have been able to destroy fightes that are so much taller than him but he was just a special athlete, my point about Parker was that he doesn`t figt like Tyson and Marciano against tall fighters, he was pretty negative v Zhang and Wilder, winning by pot-shotting.
But your point goes against you, because it shows not only that short-reach fighters can win, it shows they can with multiple styles.
