I once sparred with a guy who used this. Not sure how effective it is but that style looks cool. His style in general looks very neat and compact..
I saw some dude once doing like a praying mantis thing. Same as Jones Jr., except his fists were facing forward...or is that how he does it? And does anyone have pictures of Jones' style? I've seen it a million times watching him on PPV and such, but I can't find any videos demonstrating his defensive style.
