Ive seen Mosley badly hurt vs Forrest, I think he is the worse pick in that group. Anyway, every fighter is vulnerable to the body. Andrade look UNknockcoutable but nobody test is bady yet.
I would say Hopkins... You can't just KO a guy whom you could not hit cleanly.. It's not just about the chin, it's also avoiding not to get hit--and I would say Hopkins has the best defensive skills among those on the list..
I agree with the earlier suggestions of King Arthur and Vitali Klitshcko, both have amazing punch resistance.
Disagree about Toney and Mosley. Wlad or Vitali would KO Toney. Heck, he seemed to be in a bit of trouble in his last fight and got a gift decision. Mosley, he's got a great chin but he's wreckless at times and a guy like PW might KO him. Now Hopkins and Clottey both have great chins AND great defense. I don't see anyone at their weight classes KOing them.
gotta be Bernard Hopkins....masterful defense and a great chin, he aint getting KO'd by no1 and i'mma say JMM too, as great of a counter puncher as they come and a master of timing, he may be dropped but, i dont see him getting KO'd either also Mosley, Guzman, and J. Diaz
