Well Monty I have to disagree with you here.
Firstly regarding your conclusions regarding Mr Gardner...he won a decision
did he not? This goes against your own arguments about Judo and rules...he was judged the winner on points (unanimously).
You fail to mention that he outweighed his opponent by around 60 pounds and could not finish him off. If we say that Yoshida was not overcome by an Olympic champion who was, my god, 30 kilos heavier and had trained specifically
to fight him ....well people may draw different conclusions regarding how well Judo had equipped him. The same would go for any art, wouldn't it?
I generally agree with your points on combat
