his size is reasonably obvious, whats not clear is how you have assessed his strength and that of the scrawny student ? the immediate solution would seem to be for scrawning students to hit the gym, if they don't already do soEh, I was talking about Dan the Wolfman who is both stronger and more skilled than the people he grapples with in his videos. I think he'd be better served getting one of his scrawney students and having that student using those Aikido methods on bigger and stronger grapplers.
his students may not wish to go against skilled grapplers, they may be reserving their efforts for aggressive drunk and road ragers
