Honestly I don't see this fight going any other way than Hendo turning off Machida's headlights.
I realize that if Machida won it wouldn't be a surprise, he's a great fighter, but every time I run this fight through my head it ends with Machida on the ground limp. I honestly don't think he will be able to avoid that big shot, I know he's great at it, but in my head thinking of them fighting, I can see Hendo getting in every single time and doing the nasty to his chin (as in at least once in the fight and ending it, not every exchange).
