Thanks for all the responses, even the insulting, boorish, and rude resposnses, which I guess some people feel they need to make for some unknown reason.

WHy the hostility? This is an open forum, where we exchange opinions, in a civil and decent manner. No need to say I don't know shit about boxing. I happen to know a bit about boxing, frankly.

I still believe Floyd can't take too good a shot, and the "proof" some of the hostile responses offered that "Floyd has never been knocked down" is no proof at all. I've seen the guy wobble and bobble from shots that he was BACKING AWAY FROM that weren't even any kind of KO punch to begin with. So I still SUSPECT (that was the original post topic, remember dudes?) that Floyd and RJJ don't have such great chins, even bordering on glass jaw status.

I respect your right to differ, and to explain why you differ.

But examine yourselves closely and come up with a good reason for your hostility and uncivil words to me.

Lyle, mate, thanks for your responses, you've always been objective and fair.

Oh, and I still believe Lennox's chin was less than iron, to put it mildly. And Vargas? ODLH rocked him with just a couple of stiff shots, and it was lights out. Do you think those same few shots would have knocked out Mayorga, or Duran, or Chavez?
