Silva's chin is not as proven as the others, he gets hit much less. We have no way of knowing if his chin would hold up to a two-way war, so I wouldn't include him here. Henderson, Penn and Nick Diaz would be my top three non-heavyweights, off the top of my head. Chris Lytle was always someone I'd mention in these discussions, before he retired.
Lol. Only in MMA can someone who has been knocked down multiple times and even knocked out be deemed as having one of the best chins in the sport.atsch
Ballbags. This also happens in boxing. Roberto Duran got knocked senseless by Tommy Hearns, Luis Manuel Rodriguez got totalled by a single shot from Nino Benvenuti, and these are two of the most proven, greatest chins of the modern era. You don't know ****, you Glass-Brained Troglodyte.
