Just been watching the AJ knockouts on Sky. Looking for a chink in his armour, I would say that there were one or two fights where he was throwing lots of punches and, fortunately for him, the ones that came back missed. But the misses weren't due to him skilfully avoiding them. He has very fast hands but the fact that, in some fights, it took several punches to get the stoppage, with the opponent still standing, raises a question in my mind about the power of his punching. Maybe he isn't as powerful as he sometimes looks. Maybe some of them had glass chins. He is most vulnerable when he rushes in all guns blazing. Taking all this into account, I just wonder if, one day, a hard hitter with a good chin, who wants to mix it, might just get lucky; so far they haven't.
