Michael Bisping's ability to take a punch is the talk of the media before every Bisping fight. Today we look at the defensive flaws which leave Bisping's chin so exposed in his bouts. The chin is a vague term in combat sports - most use it to refer to a fighter's ability to take punishment to the head in general, but other times it is about the durability of the jawline alone. The truth is that while the temple is an excellent target - or vital point (depending on your martial art of choice) - it is surrounded by plain old skull, which is much, much denser and sturdier than the many bones which make up the human hand. The jaw on the other hand is full of nerves and contains moving parts - it is not built for taking punishment and a great many men have been knocked out with punches landing on their jawline or chin. To this day professional athletes are taught to protect their jaw at all costs - keeping it behind the gloves or the shoulders at all times. One only needs to listen to Bernard Hopkins or James Toney discuss their philosophies on taking punches to understand how much more affecting a blow to the jaw is than a blow to the skull. A bad chin - in the sense of an inability to take punishment - is not a particularly common thing, and the same is true of a remarkably study chin, but there hasn't been a single fighter who developed a reputation for being chinny that couldn't have benefited from some solid lessons in defense.
