GSP's timing on ducking under punches and hitting take downs is incredible. I've listened to Rogan, Chael, and others talk about how stupendously good GSP's timing on this stuff was. He basically waits for you to throw a punch or a kick, avoids the strike, and hits the take down. People always say Georges has a sick power double, which he does, but its his timing that is next level.
This is one of my favorite take downs I've ever seen GSP complete. I wish I could find a better angle. Hendricks throws a power right shot and Georges smoothly ducks under it to hit the take down.
