Anderson didn't even fight all that great. You could see he was letting too much emotion get involved when he was grabbing Chael's shorts. I don't even think he was trying to get an advantage doing that, he just wanted to hurt dude right then and there. Calm Anderson finishes that with a crisp straight right or jab and then strikes on the ground. That said, Sonnen got discouraged when he couldn't take Silva down, saw what kinda hands he was up against and threw everything into that spinning back fist.
