From Mike C at NBCSports:


Anderson Silva is not muscle-bound but he hits harder and is physically stronger than most fight observers give him credit for. What is even more surprising is the fact that fight observers cannot seem to notice how tough his chin is. He absorbed good shoots from Henderson, even Franklin, and did not even flinch.

Paul, let me share a quick story with you. When I was in Columbus for UFC 82, I was shamelessly eavesdropping as ESPN Radio's Steve Cofield was interviewing UFC middleweight Jorge Rivera. The veteran told a story of when he fought Silva in Cage Rage back in 2005. At one point of their encounter, Silva had Rivera in a Muay Thai clinch and clearly allowed his opponent to hit him in the face several times. Rivera felt he connected solidly, but when he looked Silva in the eyes, the Spider winked at him! The demoralized Rivera soon after succumbed to a TKO loss.

So yes, his chin is very underrated.
