The Machida KO was excellent. His striking is a similar phenomenon to Silva's, in that it doesn't look as though there is much force being applied but it is so sharp and quick that the opponent just cannot deal with it at all.
Also, Shogun has shown up in his best shape probably since the second Machida fight. He has looked the better fighter but we'll see if his stamina will hold up, and it won't be like his zombie impression in the Hendo bout.
I fully expect Dana to hint at Machida - Shogun III for the number one contendership during the press conference.
