I remember reading about that fight, yes...
I make no claims to have any informed opinion on judo, having never studied it...
I am aware of the story of how Kenshiro Abbe came to study aikido, so i knew he must have been quite good at judo.
To state that Abbe Sensei must have been 'quite good at Judo' is almost like saying a Rolls Royce Silver Shadow is 'just a runabout, like a Ford Fiesta'.
Hope you are well,
