Wlad got punished for trying to clinch. Corrie was a massive puncher he put guys down that never had been put down so dont know if this is a good example of wlad having a glass jaw.
that was just one from the four knock downs ... and even that it proved Wald chins is glass and can be headbutted
I can't even name 3 decent guys Shavers, Maricano, or Foreman put down that nobody else had. One or two at best. Maybe not the best question? Louis maybe the best HW in that regard, off the top of my head he gave Max Baer, Tony Galento, and Godoy the first knockdowns of their careers. But yet Louis isn't really regarded as strong a puncher as those three. Yeah, just not a good question at all if you are trying to use it as evidence of Sanders' lack of power. Rahman had no KOs of note going into Lewis bout but we can still say he's a big puncher, even if he doesn't have an impressive resume of first time knockdowns.
No, he clearly stated that he has a "glass jew." Which isn't surprising as much as its thought provoking. :think
