I have noticed in the few fights i have seen of PBF that he tucks his chin in so tightly at times, that its looks like his face jus continues on from the top of his shoulder. This along wih his defensive blocks makes it very hard to put one on his chin. Khan on the other hand leaves his chin flapping in the wind like a flag Do you think Khan can modify his defence to incorparate a similar defensive style to overcome his dodgy chin problem, or do you think this would affect his other game. Who else has a defence that would be suitable for a china chin?
This thing about Khan leaving his chin up in the air is total bull****. He is improving his defence in every fight. He still has major problems but he keeps his hands up much more than he did at the beginning of his pro career. He has a major balance problem, in that he is always leaning forward or pulling back way too much. He still has amateurish traits. The MAJOR one is he doesn't pick his shots well enough. He just lets his hands go. This simply gets him tired, doesn't score, doesn't tax his opponent and is of no real use against any fighter other than low opposition. In the ams you'll get BS points but not in the pros. He still has a long way to go but that is what experience is for.
He could do with a trainer like Manny Steward, who would really improve his defence and make him use his boxing skills.
