Lol what? Silva has one of the best chins in the game son
I think he's only been punched like 3 times in his entire UFC career, all of which being from Sonnen and he got pretty hurt by them.
I had this conversation about Mayweather before. Not ever being hurt doesnt prove you have a good chin if you've never been hit. It's not a negative because you're defence is at a point which nullifies your chin being relevent, but the only times we seen Anderson take a punch he felt them.
