How many times do you think they had to rehearse that big, exaggerated fall after the 1 inch punch? Gimme a break. I think that the 1 inch punch is real technique that works, but what a bunch of acting that was in that clip. For one thing, watch it in slow motion. Really, do it. It's actually more like a 1 foot punch. There is wind-up in this particular guy's technique. And the impact wasn't really all that devestating, despite the hammed up reaction to it.
And that magician - wow. He could unify the belts without even taking a punch. I wonder why he doesn't box or fight competitively. Hmmm....
