Best chin of this era?

[bojangles1987]

Margarito.

[M Bison]

My honorable mention is Guillermo Jones, he fought from Welterweight to Heavyweight and he usually blocks punches with his head, its unreal. The shots he took in that Lebedev fight are just unbelievable.

PEDs...
Don King fighter...

Lost respect for Jones, he is a proven cheater and he has done it more than a couple of times!
If he did it naturally I don't think he'd of had the tank to sustain those shots that Lebedev was throwing at him, I'm not saying steroids = better chin but its clearly allowed him to have an unfair advantage which a natural man in his shape and age would of likely been sparked the **** out even just from the fatigue of being rattled about that much.
