Anderson Silva is awesome. But I'm a Brazilian MMA fan, so... there would be little chance of me not liking him. The reason why I thought of these gifs is because he is super famoues for slipping punches with an astounding precision (a bunch of people, who are not familiar with MMA, end up thinking the fight is fake). And the knee was basically how he defeated his biggest nemesis for the second time, a knee while the guy was down, which is similar enough to Joel's knee.
Did you guys see this knee move? It looks great. It's the contextual move against a 'low wall'. It's easy to pull off on that standing Runner - as he is just beside a low wall.
I want to see Silva fight Jones
