I wondered about the Prescott fight. I remember the pre-fight interview and it became evident to me that something was wrong. Even my dad looked at me and said 'something aint right there'... Kahn looked terrible.

I believe he was fasting so that could explain why his punch resistance was even worse than it normally is - which is pretty poor by anyone's standards.

There are so many variables that can deem whether a punch has knockout power so the fact that Prescott couldn't KO a guy who had previously been ko'd by supposed lesser punchers, doesn't mean that much to me.
