Yep it's already up here somewhere. Personally I don't get the hype behind this video, the kick isn't anything special.
I think it's special because he's showing GSP how to do the kick correctly. We've seen GSP and other fighters throw these kicks before and they don't land with as much force because of improper technique. TKD may not be the best specialization to utilize in the octagon but I like the fact that fighters like GSP and Silva take the time to learn technique from so many disciplines of fighting, not just boxing, bjj, mt and wrestling.
but yea, saw this a while ago.
