In a sport where a bullet proof mug is about as valuable as dirt in Waterworld. There are a few fighters who seem to have an advantage over their oponents simply because they sport a sturdy chin. But it is what it is, just like how some guys are fast, tall, freakishly powerful or have a 4 inch reach over someone who is taller then them. All intricate details that make up the beautiful world that is MMA. But before I go too Frank Mir on you all lets get back to the topic at hand. Of who is the current holder of the sturdiest mandible(or jaw for short)
My top ten would go like this, no particular order as it is way to tough to call.
Big Nog - Legenday
B.J. Penn - has he ever been rocked?
Patrick Cote - Andersons best shots didnt even faze him
Rampage Jackson - just look at the size of his head
Dan Henderson - never been KOed
Sam Stout - see second Fisher fight
Keith Jardine - this is one of those joke things
Gomi - also has never been KOed
Mark Hunt - would have had the top spot if it wasnt for Manhoef
Faber - he has two
Chris Leben - see any fight besides the Anderson fight
Anderson Silva - once again has he ever been rocked?
If I had to pick one I would likely go with B.J.
