I got this from another site and this is also what I saw in the 1st 3 rounds. The last 2 were clearly Rua's in my observation.
Those who claim that Rua won the fight must have been just listening, and not really watching the fight. Because if you just listen and not carefully watch the exchange, then all you will see is what the commentators want you to see, the kicks from Rua. This is what he mostly did in much of the entire fight. Now watch the fight again without the audio on, but watch it on slowmo so you can see that most of Shogun's kicks came with a price… either a stunning straight to the face or to the upper torso. Now pay attention also to the fighter that was closest to getting in serious trouble, then you will see why Rua raises both hands to his sides whenever he gets seriously stunned. The blows that almost lead to a knockout, blows that puts the fighter in serious trouble are the ones that should count. Unless Rua kicks Machida hard enough to the head, his kicks never got Machida in trouble, In fact, it was Machida’s head kicks and charging knees that took the air off Rua. I agree it was a close fight as far as the number of exchanges are concerned. But try judging it based on which fighter really got into serious trouble and you will see why the judges scored it the way they did.
