Warning, im about to vent....
I cant comment on the chi sao, but the grappling was P*ss poor andso sh*t it wasnt even funny: he was wrong in so many ways its not even funny
the body lock takedown was cr%p you wont get the chance to just keep going because any half decent grappler, (ie not these two muppets) would keep control of the hips and put weight into you, not let go so you can spin out and look cool
The sprawl is not used when the opponent is far away, but when he is in on your hips and close, getting that fundermental aspect of the game so fecking wrong doesnt bode well ...as for the actual takedown how the hell he managed to NOT get any penetration from that range ill never know, no forward momentum, rubbish finish un realistic body angle, weight going down not forwards its all there...by that i mean everything you are ever told NOT to do by a grappling coach
As for the defence, no level change just stand strong and kick over there head, jesus did people actually pay for this seminar?
the single leg take down were better, although not enough level change and no one falls over like that, and i like the heel hook sweep but you probably need both feet on the hips to make it work,
as someone else said just go to a grappler for this stuff
