prescott caught khan early and unexpectedly. even khan didnt know his chin was that glass before that fight. being cold and getting clocked makes it much easier to be ktfo. maidana hits harder and is a much better fighter than prescott. Getting hit while warmed up and already taken a few hits before the 10th round, khan's chin was 'warmed up' to getting hit a bit. and even then khan knew a bit of what to do like run hide and cover up when he was hurt cause he had been there before.
Prescott , but only because i have seen some of his other fights and he puts people to sleep, where as maidana stops fighters by tko. Both have close to peanuts for brains though.
Prescott's power seems to be overrated at this point, not by much, but definitely overrated. He got Khan with some good, clean, powerful shots to take him out...but after that, Prescott has not only shown how limited he is, but also that his power is not a fight changer like it is with Maidana. Apart from the 1st round knockdown, Vazquez was not troubled by Prescott's power, nor was Mitchell. And even before that, if I remember rightly...before the DQ, nor was Toledo.
Prescott's power is HUGELY overrated. The man's not even a puncher, he's like on of those awful Brazilian fighters who are marketed as a KO puncher, then go over to the USA to fight a non-durable journeyman and can't even hurt him.
